check_nanosleep()

gboolean check_nanosleep

(

void

)

check_nanosleep:

Check if nanosleep() is accurate enough for sub-millisecond sleeping. If it is not good enough, we're skipping the minor sleeps in LogReader to balance the cost of returning to the main loop (e.g. we're always going to return to the main loop, instead of trying to wait for the writer).
