* The enabling of INT messages is one of the criteria that's also included in the Debugger's
* checksEnabled() function, and therefore in fDebugCheck, so for maximum speed, we check fDebugCheck first.

*
* NOTE: By wrapping this in MAXDEBUG, we're effectively eliminating the need for any checkIntReturn() calls;
* onIntReturn() generates a lot of noise, via dbg.messageIntReturn(), and because there's no way to be be sure
* we'll catch the return (or for some interrupts, *whether* they will return), it's safer to disable this
* feature unless you really want it.
