I haven't heard about this, I haven't seen this, and don't have an example
or someone who can reproduce it.  Things don't get fixed unless they are 
reported and reproducible.  The example cited before looked like a program
bug in locking a hardware interrupt handler.  When you "pause" you spend
all of your time in real mode, so a reflected HW interrupt is much more
likely than one that stays in PM.  Since only RM reflected interrupts will
turf up improperly locked memory, you might need to pause to find them.
