Some time back I experienced deadlocks with FreeBSD 5.4 and either  
libthr or libpthread.  linuxthreads had no issue.  Other machines  
with different hardware did not have the problem.

It looks like I'll be able to perform some testing on that machine  
sometime early in the new year.  What is the correct forum for  
discussing this when I get the opportunity to look into it again?
