I'm no Win32 expert, just though that the code in the win32process module (which is part of win32all) probably already provides code in this area.

With a Win32 flavor, which isn't what I need here. There is no distinct "wait for process" function in Win32, it's just another application of the very cool WaitFor{Single,Multiple}Object(s)[Ex] APIs (which can "wait" for sets of "handles" to "do something": kinda like Unix select(), except not braindead ).

That's fine, but what I specifically needed (for a Zope Corp project) was a Unixish waitpid() workalike. MS already did most of the work for that in their _cwait function, so it would be silly not to reuse it. BTW, a google search suggested Borland also supports a cwait function, but I have neither a Borland compiler nor time to worry about that platform. You didn't worry much about the Cray T3E when implementing Unicode either .

Another candidate for Windows emulation would be os.kill(). win32process has TerminateProcess() which could probably be used for this (no idea however, how you get from a PID to a process handle on Windows).

I'm not looking for random functions to implement; if I need an os.kill()-alike, I'll do one, but I don't expect the need. TerminateProcess() is a dangerous function on Windows (read the docs). If you want to risk it, you go from process pid to process handle via the Win32 OpenProcess() function.
