Teach unix_latch.c to use poll() where available. poll() is preferred over select() on platforms where both are available, because it tends to be a bit faster and it doesn't have an arbitrary limit on the range of FD numbers that can be accessed. The FD range limit does not appear to be a risk factor for any 9.1 usages, so this doesn't need to be back-patched, but we need to have it in place if we keep on expanding the uses of WaitLatch.
