No, I don't think pthreads does that, remember looking for at a year
back or so.

Adressing each OS I've tried:
	- linux, threads were soddy a year or two back, people
	say it is ok now.
	- Solaris, they rock.
	- AIX, they suck. Well, we encountered a lot of sigsegvs that
	appeared to be caused by fault memory allocation when threading.  

And I know that FreeBSD has pthreads support.

I don't know about others, but if they have thread support, it should
be pthreads, and if not, I doubt thats the only problem there will in
porting the stuff. (and is it a unix that people will be installing
gpilotd on ?)

I think threading should be limited to a thread for pilot operations
and a thread for corba calls. That way orb calls won't delay a sync. 

Also, then a pilot should be marked as busy, so that a request_for_*
on that pilot reesults in a BUSY error.

Also ensuring that such things as file operations happens with the
calling programs permissions.

We sort of halfway agreed on letting the global version use
/var/spool/gpilotd/USER, and the local in .gnome/gnome-pilot.d/.

I doubt it'll be quick, so I'll create branch for that development.
