I've uploaded a newer version of this file.  It addresses most of the 
problems found by others up to this point.  I'd appreciate someone 
testing this with Comeau (and other compilers) to see if I've fixed 
the syntax problems.  VC++ is too forgiving on many of these things, 
making it difficult on me here.

I've narrowed the deadlock down to the pthread implementation of 
boost::recursive_mutex.  It's caused by a race condition present 
because of the multiple mutexes used here.  I've yet to figure out 
precisely what causes the race condition in order to fix it, 
however.  I'd appreciate pthread experts looking at this not only to 
fix the deadlock but better yet to provide a more optimal solution.  
If there's such an expert that wants to take this on I'm more than 
willing to answer questions and provide any other assistance they may 
need.  The pthread implementation is the last hurdle that needs to be 
overcome before we figure out where to go next with this library.

Thanks,
