	You're quite right - except for the fact that the OMG documents CORBA
and the C binding quite extensively. However if you're competant you
should be fine without docs.

	Not really; there is some support there - there are several known
problems with the thread support. It's not unrealistic to expect to be
able to complete the thread support - talk to Sebastian about it.

	Clearly, if a request can be processed in multiple threads then you
need to add all manner of locking primitives all over the shop. This is
why primarily we use the re-enterant model to provide the illusion of
threading, without the need for (dead) locking. :-)
