* However, the PCjs approach requires the CPU to continue running. One simple solution to this dilemma:
*
* 1) opWAIT() sets a new opFlags bit (OPFLAG.WAIT)
* 2) When stepCPU() sees OPFLAG.WAIT, it checks for interrupts; if none, it rewinds the PC back to the WAIT
* 2) Rewind PC back to WAIT
* 3) Whenever stepCPU() detects OPFLAG.WAIT, call checkInterruptQueue()
* 4) If checkInterruptQueue() detects an interrupt, advance PC past WAIT before dispatching it
*
* Technically, the PC is already exactly where it's supposed to be, so why are we wasting time with steps
* 2 and 4? It's largely for the Debugger's sake, so that as long as execution is "blocked" by a WAIT, that's
* what you'll see in the Debugger. I could make those steps conditioned on the presence of the Debugger,
* but I feel it's better to keep all code paths the same.
*
* NOTE: It's almost always a bad idea to add more checks to the inner stepCPU() loop, because every additional
* check can have a measurable (negative) impact on performance. Which is why it's important to use opFlags bits
* whenever possible, since we can test for multiple (up to 32) exceptional conditions with a single check.
