Right in the Overview of the NSMapTable documentation:

"It can contain arbitrary pointers (its contents are not constrained  
to being objects).

"Note that only the options listed in “NSMapTableOptions” guarantee  
that the rest of the API will work correctly—including copying,  
archiving, and fast enumeration. If you use other NSPointerFunctions  
options, the map table may not work correctly, or may not even be  
initialized correctly."
