60 * On macOS < 10.9, poll() with nfds=0 failed instead of waiting for

64 * instead of waiting for the timeout, resulting in busy-looping.
65 *
66 * On Interix, poll() apparently only works for files in /proc.
67 *
68 * The "legacy" build flavour in our CI machinery defines BROKEN_POLL
69 * on whatever platform is in use (normally Linux) to force use of the
70 * same select()-based poll() emulation that we use for macOS, Interix,
