In process calls certainly should obey the single thread model. Look at
the use of pd_call_lock in poa.cc. Note that recursive calls are
permitted, though, so you can't deadlock against yourself doing purely
local calls. (You can still deadlock if you call out of process, and the
other process calls back in, though).

What makes you think it's not working?

Cheers,

Duncan.
