I realise this, but that handler doesnt get the signal either...
From: http://www.python.org/doc/current/lib/module-thread.html
"Threads interact strangely with interrupts: the KeyboardInterrupt
exception will be received by an arbitrary thread. (When the signal
module is available, interrupts always go to the main thread.)"

I don't know what to make of this, except that KeyboardInterrupt isn't
always raised in the main thread, unless you use the signal module
somehow.
