Need a way to ensure a process is dead #33

Closed davidw closed 10 years ago

davidw commented 10 years ago

I need some kind of call so that I can ensure that when it returns, or sends me a message or something, the underlying process is really and truly dead.

Since I'm calling this from terminate() of a gen_server, I think something that just plain blocks is probably what I'm after.

This can be done via the monitor flag, it seems. Perhaps wrapping it up in a command would be convenient.... I'll have a look.

I created a stop_and_wait command here:

I fixed this slightly in another, subsequent commit:
