But it doesn't look like you're using a seperate thread at all (?)
I'm  using pd-0.36-devel still, so maybe things are different now, but if so 
that would have been quite a radical reworking of PD, to have the message 
processing be in a seperate thread than the audio.

Again, I'm a bit confused. I had always thought, that unless you launch a 
thread on your own, that PD was single-threaded, and that it relied on 
message processing to be fast enough to not cause audio dropouts  - hence 
there seems to be no reason at the moment to make your functions thread-safe. 
Now of course, it would be nice if your external worked off-line in an other 
thread, in which case re-entrancy might be then a factor.
