Also, just to sanity-check that I understand things correctly: Python signal handlers *are* reentrant, in that a signal handler can be interrupted by another signal, is that right? Is there any general recommendation on how to write signal handlers in order to manage that?
(Antoine, I *so* wish I could be doing less with signals and signal handlers right now. Alas, I have a combination of a SIGTERM-happy runtime environment and a long-story situation involving wacky multiprocessing to avoid issues in someone else's C library that make that impossible. So instead I'm trying to write a general library to help simplify the task, and so thinking about a lot of slightly nutty corner cases...)
