NSMutableAttributedString, NSFontAttributeName, and reference counting

If I allocate a font object for use with NSMutableAttributedString and 
assign said font to the string using the addAttribute method, will the 
reference count on the font be incremented?  (I assume that if the 
answer is yes, then removeAttribute will decrement the reference count.)

As a bonus question, can I observe this in the debugger (seems like a 
useful skill in order to avoid similar questions along these lines in 
the future)?  If so, how is that accomplished.
