This is the "disk validator."  It is started whenever you mount a volume
whose bitmap has not necessarily been flushed. The validator runs through
the directory structure checking that there are no inconsistancies.
My recent posting (validate) will force this without you having to
do a reboot.

Not that the validator is NOT like fsck.  fsck will repair a file system
in place.  The validator will only tell you there is a problem without
fixing it.                           -- Darren
