jdolecek 24ba90929c Avoid using microtime(9) for atime/mtime, we don't need to have it 
THAT accurate and microtime(9) is painlessly slow on i386 currently.
This speeds up small transfers much. The gain for large transfers
is less significant, but notable too.
Bottleneck was found by Andreas Persson (Re: kern/14246).

Performance improvement with PIII on 661 Mhz according to hbench (with
PIPE_MINDIRECT=8192):
