Yep, I've seen this.

> What I would suggest for your operation is spawning a dedicated thread
> to handle FOO requests.  Whenever FOO gets called, it should send a
> message to that thread, then block to wait for a response.  That
> thread should wait for requests, and for each one should handle the
> request and send a response before waiting for the next request.  This
> will guarantee each request will be handled in order and will not
> overlap.

That sounds awfully complicated and I was hoping there was an easier  
solution. Anyway, thanks for the advice and I'll dig some more into  
the world of threads/semaphore/mutexes and whatever else there is.
