Well, it's speculation on both our parts :-). ISTM we'll need an 
explicit event loop to check the shmem (or whatever we use to simulate 
signals) every so often - maybe that will be easy, I don't know - I'm 
interested to see what turns up. (Of course, if we were threaded we'd 
just need a thread to watch for the event ...)
