[python-win32] win32com.client - How to raise an exceptionafter timeout

[Roger Upole]

The question is probably better addressed to whoever
develops the COM application you're calling.  There's
probably no real general solution.

If the application doesn't have any built-in abort
mechanism or asynch processing, it may not
be safe to just kill it.  You could wind up with a
reference to a corrupted object in your
main thread, causing crashes (or worse).

After more research, I believe there is no answer for this.  I'd like
to write a PEP for this problem but I'm not sure I know enough.  Can
anyone help?  Is this perhaps a better question for the Python users
or developers list?

Thanks,

Greg
