Change subject: IMPALA-6449: Use CLOCK_MONOTONIC in ConditionVariable ...................................................................... IMPALA-6449: Use CLOCK_MONOTONIC in ConditionVariable ConditionVariable is a thin wrapper around pthread_cond_*. Currently, pthread_cond_timedwait() uses the default attribute CLOCK_REALTIME. This is susceptible to adjustment to the system clock from various sources such as NTP. This change fixes the problem by switching to using CLOCK_MONOTONIC instead. This change also get rids of some usage of boost::get_system_time() which suffers from the same problem.
