mpv/input/input.c
uau 24802b1def Use a single select() for both key and slave input 
Previous code used two separate select() calls one after another, so
that whenever it was running select() on one set of fds events in the
other set would go unnoticed until later. Now there's a single select()
which allows reacting immediately to any input source.

The behavior of the new code differs somewhat from the old; for example
multiple fds that stay readable are no longer handled in a round-robin
fashion and the total amount the process sleeps can differ. Some tuning
might be required later.
