But in that case aren't they just using the libc "do nothing" stubs? Or is
the X server loading libpthread.so via it's dynamic loader/dlopen?
Hmmm...ok, looking it appears thread enabled X apps have to call into Xlib/Xt
to say "do threading". So, just the apps are responsible for getting
libpthread linked in?
