That's kinda what I was hoping ... is it something that could be
seamlessly integrated to have minimal impact on the code itself ... even
if there was some way of having a 'thread.c' vs 'non-thread.c' that could
be link'd in, with wrapper functions?

Tha again, has anyone looked at the apache project? Apache2 has several
"process models" ... prefork being one (like ours), or a 'worker', which
is a prefork/threaded model where you can have n child processes, with m
'threads' inside of each ... not sure if something like that coul be
retrofit'd into what we have, but ... ?
