I suspect this isn't always possible, all it takes is for some service
the program uses to be implemented in a dlopen()ed library, and for that
to need libpthread and you have a massive breakage!
This could happen if (say) the dns lookup code was implemented using threads.
(that one is unlikely, but who knows what a PAM module might do).
