	Dave Mitchell showed me the error of my ways with regards to client
	server thread programming.  Fixed the handler optimized for memory so
	that no yield()s are necessary anymore.  The whole thing now gets
	through the test suite more than 25% faster for that part.
	Scalability to many more threads should now be a lot better too.

0.07	14 August 2002
	Removed (possibly premature) optimization from T::C::Thread
	_handler: it now doesn't zap the local threadspace anymore.

0.06	13 August 2002
	Handed over freezing and thawing operations to Thread::Serialize.
	Added dependency to Thread::Serialize in Makefile.PL.

0.05	6 August 2002
	Fixed "onbelt" in T::C::Thread so that it won't hang if the belt is
	shut down.  Needed for Thread::Pool and in general useful.

	5 August 2002
	Added index functionality to "peek" and "peek_dontwait" to all
	sub-classes and added documentation for it.  Needed for Thread::Pool.

	Finally got the T::C::Thread implementation getting through the
	test-suite reliably.  Problem was caused by my misconception that
	cond_wait would always regain the lock() after being signalled.  It
	does not.  This should have been in big red letters in the
	threads::shared pod.

	Added methods "shutdown", "thread" and "tid" plus documentation.

	3 August 2002
	Adapted test-suite to use many more combinations of possible
	settings.

	2 August 2002
	Added new "optimize" field parameter to allow you to select an
	implementation optimized for speed (T::C::Array and T::C::Throttled)
	or for memory (T::C::Thread).

	Added new implementation of Thread::Conveyor based on using a
	seperate thread for keeping the belt: Thread::Conveyor::Thread.

	Move basic parts of Thread::Conveyor to Thread::Conveyor::Array.
	Which should allow for other implementations of the conveyor
	metaphor.

0.04    1 August 2002
	Added internal method "_belt" to get at the actual belt, for both
	the normal and the throttled belt.

0.03	31 July 2002
	Added internal methods "_freeze" and "_thaw" so that we can move
	to a different serialization scheme or other optimizations without
	having to change all the sub-classes as well.  First user is
	Thread::Conveyor::Monitored.

	Added "maxjobs" and "minjobs" method in Thread::Conveyor that will
	die when they're called (throttling only takes place in
	Thread::Conveyor::Throttled).

	Fixed problem that would cause throttling to not be switched off
	when the "maxjobs" method was specified with an undef value.

	Added methods "clean" and "clean_dontwait" for cleaning the belt
	to both Thread::Conveyor and Thread::Conveyor::Throttled.  Also
	added documentation for it.

	Added internal method "_clean" for obtaining frozen contents of
	the belt to both Thread::Conveyor and Thread::Conveyor::Throttled.
	This was needed for Thread::Conveyor::Monitored.

0.02	30 July 2002
	Adapted Thread::Conveyor to default to a throttled conveyor belt
	automatically if no specific parameters specified.  Now allows for
	specification of throttling settings in a parameter hash reference.
	If unthrottling is specifically specified, returns to the old
	unthrottled behaviour (where the object is just an array reference),
	thus keeping the old execution speed.

	Added helper class Thread::Conveyor::Throttled to allow for throttled
	conveyor belts that block if there are too many boxes on the belt.

	Fixed some documentation nits.

0.01	25 July 2002
	First version of Thread::Conveyor, which started life as
	Thread::Queue::Any.
