Dunno, Mike, could you ask Elliot ? Anyways, I plan to let orb methods run
in one thread alone, and the other threads won't do any orb stuff. Thus
from ORBit's point of view, it'll look like it is a single process.

Cast in stone then.

Either we could "pthreads is POSIX, support or die" and use pthread_mutex*
calls for locks, or we could make a more or less redundant wrapper layer
on top on pthreads.

Or a less redundant layer, that eg. had calls like g_list_lock(GList*),
g_list_try_lock(GList*) and g_list_unlock(GList*), which uses a ghashtable
for matching pthreads mutexes with glists (and other g_things). 

Perhaps there already is such a set of methods ? If not, it might be
generic enough for other uses.

But no can do. uids are still on process level.

(btw, having been bartending 10 hours last night, I think I safely can say
I won't be touching much corba stuff this weekend).
