Not sure about NPTL support in non-Linux-based operating systems (Solaris,
BSD, etc), but I'd be surprised if they supported LinuxThreads. Thus,
shouldn't NPTL really result in a *more* portable application?
NPTL vs. LinuxThreads is a purely Linux-specific (well, glibc-specific,
perhaps) issue, it is merely an implementation detail of the POSIX
pthreads functions which are present on other UNIX variants. A portable
application should not care which (if either) is being used.
I'm presuming that the fact that setuid calls with LinuxThreads do not
change the user ID on all threads is a violation of the POSIX pthreads
specification.
