control-c and threads

[Srikanth Mandava]

Hi!

When a signal handler is registered in the main thread and
"control-c" is entered, the child thread is getting the
KeyboardInterrupt exception(The documentation says the main thread
MUST receive the signal handler function call if handler is
registered).

In python 2.2.1 the main thread was always called with
the sigint signal handler which was registered. In my case the
child thread is waiting on stdin using "raw_input" function. This
seems to be causing all sorts of strange behavior in the program
once the child thread gets the keyboardinterrupt exception and
eventually leading to seg fault on a sys exit .

Any idea why this is happening in 2.3.1? This scenario worked in
2.2.1. Is this fixed in 2.3.2?.


Thanks
Srikanth

Do you have a minimal example that shows this behavior? I'd be happy
to run it with 2.3.2 and test it out...
