[LaunchMON-devel] Code added to work around a bug in NPTL POSIX thread debug library

[Dong H. A. <ah...@ll...>]

FYI, There appears to be a bug in a version of the NPTL thread debug 
library where its td_thr_get_info call (a call to provide thread-related 
information to the debugger. That function) has a conditional statement 
whose condition is determined based on an uninitialized value. Looking 
at its source code, this condition seem to only occur when the target 
thread is the main thread. So, I am working around this by not relying 
on this call for the main thread.

I've added the work around to the main 0.7 branch. So, if you see some 
odd intermittent thread/process tracing errors, you might want to pick 
this up from the main branch.

Best,
Dong
