*
* On macOS >= 10.12, poll() with nfds=0 succeeded immediately
* instead of waiting for the timeout, resulting in busy-looping.
*
* On Interix, poll() apparently only works for files in /proc.
*
* The "legacy" build flavour in our CI machinery defines BROKEN_POLL
* on whatever platform is in use (normally Linux) to force use of the
* same select()-based poll() emulation that we use for macOS, Interix,
* and any platform that lacks a real poll(), so that we can test it
