Ah, that does kind of suck.  I am not making property changes to change out of order, but to toggle CL_QUEUE_PROFILING_ENABLE in order to determine optimum kernel group size first time / or when hardware/driver changes are detected since the last run of the program.

I do not remember, but I thought just leaving profiling turned on was a slight performance hit.  Guess I should re-test that. I never submit commands to a given queue on more than one thread or change this while something is queued, but of course one cannot assume this is always done by everyone.
