The problem:
RuntimeError: dictionary changed size during iteration
I don't know if the setup with the pids in a dictionary is the best way to
manage a pool of processes... I'll leave it others, presumably more
knowledgable, to comment on that. :-) But I can tell you how to solve the
immediate problem:
for pid in procs_dict.keys():
No, keys() produces a list (which is what is wanted here).
It's iterkeys() that produces an iterator which would reproduce the OP's
problem.
And then, in Python3, keys() produces something else altogether (call a
view of the dictionary) which would provoke the same problem, so yet
another solution would have to be found then.

I'm afraid this will do the same exact thing. A for loop on a dict
iterates over the dict keys, so both statements are strictly
equivalent from a practical POV.
