More changes from FreeBSD, including:
o Only poll file descriptors when needed.
o Change the way timing is achieved, counting scheduling ticks
instead of calculating the elapsed time via gettimeofday().
o Prevent an overflow when polling.
o Use curthread instead of _thread_run.
o Remove extra spaces; indent.
