i dunno if this is news to anyone, but apparently
(the source comment says "copied from OS9 code")
the NMI is masked and switched from edge to level triggered before
sleeping and unmasked and returned to edge triggered after wake.

is the low level sleep handler doing this correctly ?

refer to:
xnu-4-2/iokit/Drivers/platform/drvAppleNMI/AppleNMI.cpp
