This is very outdated, sys_arch_timeouts() is not needed anymore circa 
2011.

You are right, CLOCK_REALTIME (the gettimeofday() timing source) is not 
a nice timing source to get elapsed time, the port is now using 
CLOCK_MONOTONIC. However I doubt that having used CLOCK_REALTIME instead 
of CLOCK_MONOTONIC was enough to qualify the whole port as being 
miswritten.

Why didn't you propose a patch when you noticed that several years ago ?
