Hi,
attached patch replaces select() by pselect() in the gpsd main loop. This
should make gpsd behaving nice when idle and avoids a race condition when
multiple signals arrive shortly one after another.
if COMPAT_SELECT is defined, the code should behave exactly as it did before,
for systems where pselect() isn't available. COMPAT_SELECT needs a
configuration variable.
