I'm trying to port some python code that uses the Popen3 class returned from
popen2.popen3 on linux. This isn't available on windows, so I thought I'd
try it using win32process.

I figured out a way to call win32process.CreateProcess that actually spawns
a process, but calling win32process.TerminateProcess on the handle it
returns fails with 'Access Denied'.

What would be the typical way someone would spawn a process and later kill
it?

Sample Code:
import win32process
si = win32process.STARTUP_INFO()
details = win32process.CreateProcess('foo.exe','foo.exe
',None,None,False,0,None,None,si)
win32process.TerminateProcess(details[0],99)
