Hi everyone,
I'm in the process of writing some code to defer signals during critical
regions, which has involved a good deal of reading through the CPython
implementation to understand the behaviors. Something I've found is that
there appears to be a lot of thoughtfulness about where the signal h
... Reading through more of the code, I realized that I greatly
underestimated the number of interruptible operations.
That said, the meta-question still applies: Are there things which are
generally intended *not* to be interruptible by signals, and if so, is
there some consistent way of indicati
I'm taking it from this thread that suppressing signals in a small window
is not something anyone in their right mind would really want to attempt.
:) (Or that if they did, it would have to be through a proper change to the
runtime, not something higher-level)

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?

I had not -- thank you!

limb that particular mountain yet, but I
figured I'd see what obvious holes other people could poke in it.
Thanks for your help!
