Keeper code is just a conditional resynch:
if (delay > myQ) { sc_wait(delay); delay = 0; }
By calling wait(delay) the simulation time will advance to where the caller has got to while running other pending processes.
Or where a thread needs to block to wait for a result from some other thread:
while (!condition_of_interest) { sc_wait(delay); delay = 0; }
Generally, we can choose the quantum according to our current modelling interest:
Transactions may execute in a different sequence from reality: sequential consistency compromised ?
