Is the NeXTstep 2.1 kernel threadsafe?  The threads documentation
encourages you to bracket most lib calls with mutex semaphores, 
but what about functions like msg_send and msg_rcv?  Apparently
in 3.0, the kernel is threadsafe, but non-kernal OS fnctions like
the nameserver are not.  Also a special call is needed to make 
the Objective-C runtime threadsafe.  I'm concerned about these 
details in 2.1, 2.2 at the moment.
