Patch fixes the issue, but I think the commit message could be a bit
clearer by shuffling the phrases around.
What do you think about:
"""
This fixes a regression introduced by
4028fb1c794ef2a212f22b024b1c39f460439e7b, where clients_num was not
updated correctly anymore.
There is no reason to cache the number of elements on that list, as the
expected number of clients is quite small.
"""
No need to send another version, if you adjust the message.
