zero-shot timers race condition demo:
-------------------------------------
  This trivial project counts 7-bit pending messages. 
  Each message calls a zero-timer that resets the counter.

  To see the race condition, just move a 14-bit high resolution fader/knob,
  and then searchin the log when "ga" becomes "2"

  I would happily accept any lower-performance option that would remove this issue.
  Thank you.
  
  
Just the rules:
---------------
  OK behavior:
    228454 - RULE 1.2:1 assignment: (ga=0) = 0
    228458 - RULE 1.1:1 expression: (ga=ga+1) = 1
    228458 - RULE 1.2:1 assignment: (ga=0) = 0
    228458 - RULE 1.1:1 expression: (ga=ga+1) = 1
    228458 - RULE 1.2:1 assignment: (ga=0) = 0


  Undesired behavior:
    228461 - RULE 1.2:1 assignment: (ga=0) = 0
    228465 - RULE 1.1:1 expression: (ga=ga+1) = 1
    228465 - RULE 1.1:1 expression: (ga=ga+1) = 2                  <<<<<<<<<<<<<<<<<<<< my problem
    228465 - RULE 1.2:1 assignment: (ga=0) = 0
    228465 - RULE 1.2:1 assignment: (ga=0) = 0
