35/*! Appears to be some sort of interface between RMMapContents and markers.
36 
37 \bug lots of arbitrary-appearing \@synchronized blocks. Old mailing list traffic 
38 claims they're needed, but no one seems to know why. If the #set ivar needs to be guarded,
39 should be done by \@synchronized(self) and not \@synchronized(sublayers). Maybe the guarding
40 is needed because of Core Animation thread interactions.
