"man poll" returns "No manual entry for poll" on my MacOS X 10.3.7
machine, Darwin 7.7.0.  Nevertheless, <sys/poll.h> exists, as a
redirection to <poll.h>, which describes itself as:

    poll - select(2)-based poll() emulation function for BSD systems.

    int poll (struct pollfd *pArray, unsigned long n_fds, int timeout)
