Python on Windows - how to wait for multiple child processes?

Question

How to wait for multiple child processes in Python on Windows, without active wait (polling)? Something like this almost works for me:

proc1 = subpr         


        

Answer 1

Twisted has an asynchronous process-spawning API which works on Windows. There are actually several different implementations, many of which are not so great, but you can switch between them without changing your code.
