Please excuse me with jumping in but I have a related question.

If one had a dynamic executable built on a LinuxThreads system (glibc without 
NPTL support), will it have this problem when ran in a modern glibc 
environemnt? Or will it need a recompile against NPTL glibc to benefit from 
all changes?
