Comment(by infinity0):

 Turns out you can't send SIGINT on windows (python throws OSError), and
 python transforms SIGTERM on windows into TerminateProcess (in
 subprocess.py, it defines kill = terminate for windows platforms) which
 behaves like a SIGKILL.

 One way of filling in the gaps is to have subproc manually translate
 SIGINT into a CTRL_C and SIGTERM into a CTRL_BREAK, both of which are
 possible in Python. This is the most cross-platform solution even though
 it is non-standard (and no such standard exists). Let me know if you want
 me to proceed with this. The other, simpler option is just to ditch signal
 handling / graceful shutdown on windows, including the "2-INT shutdown"
 behaviour that is part of the PT spec.

 I hate Windows.
