[Mono-devel-list] Threading, NPTL, libgc (beta2)

I've been continuing to try to explore the odd behavior on gentoo, and have 
made the following observations (if these are useless, I apologize):

a)  I ran XSP multiple times against the xsp test suite, while running a full 
trace in mono.  The only interesting thing of note, is that 4 different 
executions caused the hang at different points.  For example, one execution 
hanged during the HttpWriter.Clear, and another time in the IPEndPoint 
constructor.

b) I also made a call trace for the executing xsp process once it was hung.  I 
have attached the file containing the mono related bits, hopefully this helps 
provide some insight (though doesn't mean much to me).

If there is any other information I can give you, please let me know, I would 
love to help.

Thanks!
  Mike
