[python-win32] Killing a subprocess spawned by a service

[Mark Hammond]

The other solutions I can think of are likely heavier and harder than 
arranging to spawn the child without shell=1 - so I'd suggest tackling that.

Or *maybe* - you could do something like spawning a thread in the child 
process to read from stdin - that's likely to block until the cmd.exe 
parent is killed, in which case the read would return with an error - at 
which point the child could terminate itself...
