    poll()'s timeout value is measrued in milliseconds. Using a 32bit
    value, as implied by using 'int' for the type, limits the mximum timeout
    to be 2^31-1 milliseconds, which means about 24 days. Believe it or
    not, people are complaining about this. Changing the timeout to a 64
    bit millisecond timeout would lift the limitation from the API's POV. I
    don't know what limitations exist in the kernel itself.
