While trying to debug #3572, I noticed that I would frequently break in the midst of gettimeofday and that the routine get_adjusted_boot_time had to take and release locks. Furthermore, we don't want "adjusted" boot time, which could go forwards or backwards depending on the adjustment (such as setting the clock used by gettimeofday() to the network time)
