 Good to know, sounds like that may be a better solution for this 
 particular situation and esoteric enough to not warrant maintaining the 
 _thread_dump_info() call in order to support older BSD systems that 
 perhaps predate or don't support the SIGINFO behavior.  For what it's 
 worth, this bit of code has in fact been used to debug the threading 
 libraries in the past.

 Thanks for your suggestions and insight.
