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
