that code is part of an outer loop which subsequently calls info_read and
select. this whole procedure (perform, info_read, select) is done until
there is no more work to do.

one thing though -- the code does a select(..) without at timeout, so unless
there is activity on the file descriptors this will block infinitely. is
this harmless or does the multi api assume that select times out
periodically?

It might very well be me who's missing this here.

When that loop ends, it doesn't signify anything else than that the app
should wait for more action on the socket(s) or wait for a timeout and then
do it all over again. Untill 'still_running' turns zero.

If that was what the python code does, then I was wrong.
