IIUC, the reason for this is that gettimeofday is affected by wallclock
changes (think NTP):
CLOCK_MONOTONIC
Clock that cannot be set and represents monotonic time since
some unspecified starting point.
...so by preferring CLOCK_MONOTONIC, the mtab locking code isn't
affected by clock jumps or skew. Bjorn, is this correct?
