Hash :2e312772 Message :Disable lazy gettimeofday/clock_gettime comparison
The benefit of this optimization is questionable for the following
reasons:
- libevent uses CLOCK_MONOTONIC_COARSE which is fast enough (on my
desktop CLOCK_MONOTONIC/CLOCK_MONOTONIC_RAW works 40/50 millions of
ops per second, and CLOCK_MONOTONIC_COARSE is faster)
- libevent has caching of time (EVENT_BASE_FLAG_NO_CACHE_TIME)
So I don't see any reason for using one more caching - lazy comparsion
(whatever you call it).
