[issue23395] _thread.interrupt_main() errors if SIGINT handler in SIG_DFL, SIG_IGN

[Andre Merzky]

Andre Merzky added the comment:

Attached is a patch which seems to resolve the issue for me -- this now triggers the expected `KeyboardInterrupt` in the main thread.  For verification one can run the unaltered code as provided by Thomas.

I would very much appreciate feedback, to make sure that the semantics is actually what one would expect.  The patch is against the 2.7 branch from https://github.com/python/cpython.git, and I did not test it against any other branch.

I also opened a pull request (https://github.com/python/cpython/pull/39).
