[TIP] Testing Windows CTRL-C handler under Tox

[André Caron]

Hi all,

I'm writing a context manager for asyncio that will set the result on a
future when CTRL-C or SIGINT is received and I have an issue with the
Windows part.

When testing on POSIX platforms, I use "os.kill(os.getpid(),
signal.SIGINT)" to execute my signal handler.  I'm trying to convert this
to some Windows equivalent an I'm getting a surprise.
