292 	@discussion The OSAsyncReference64 structure passed to async methods holds a reference to the wakeup mach port, which should be released to balance each async method call. Behavior is undefined if these calls are not correctly balanced.

351         Remove the first mapping created from the memory descriptor returned by clientMemoryForType() from IOUserClient's list of mappings. If such a mapping exists, it is retained and the reference currently held by IOUserClient is returned to the caller.
353         @result A reference to the first IOMemoryMap instance found in the list of mappings created by IOUserClient from that passed memory descriptor is returned, or zero if none exist. The caller should release this reference.
