1ae23ad935 - MONITORX/MWAITX: It is possible that MWAITX wakeup from timed mwait but APIC timer was still not reset. 
A corruption would happen if MWAIT is called again to setup the timer while it still running from previous time.
  Also spurious wakeup could possibly happen as timer will send wakeup when it stops counting.

0730ff4c4a added a comment for future: some memory operations must be done atomically 
these are include LOCKed RMW of course and also a lot of others
in the future it will be very hard to find all the cases that must be atomic so better to start marking them already now
try to mark every RMW case for atomicity requirements
