This can be worked around, depending on the level of inelegance you're
willing to accept. A third watchdog process could wait on the launcher
being terminated, and use that to terminate the child Python.exe
process. Alternatively, the launcher could inject a sentinel thread
into the Python.exe process using CreateRemoteThread. Both approaches
would work for any target implementation or bitness of Python.
