Feature #7025: way to wait for closing with IO.popen object

Hello.
I noticed that it seems, if you do:
IO.popen("something", "w")

there's currently no way (without using a block form? [1]) to tell that this process has exited (or do correct me if I'm wrong).

So consider this a feature request for such.
Thanks!
