1) Have all constraints check and localzation now
2) Here are benchmarks (worst case)
   log infra overhead      -- 1010 cycles (pptest)
   log synch activation    -- 1230 cycles
   log async activation    -- 2061 cycles
   log constraint check    -- 476  cycles
   log localization        -- 141  cycles
3) #MEAS are defined in log.c, log.h, process.h and cli1.c
4) chkpt before doing RTA simulation
