You could ask. At very worst, you'll find someone explain to you why
it shouldn't be done. I suggest using the python-ideas mailing list;
people there are usually reasonably friendly, though occasionally you
find a caustic response to a dumb idea like "Python should use braces
for indentation" :)

Yeah, I went looking for it and came across that, but wasn't sure if
that was it.

Now I look more closely (ie: look at the actual source code), I see
that it probably is the function I was thinking of. Might need a docs
patch to make it clear that this iterates over getaddrinfo() and
attempts them all in succession.
