I recall a discussion about the design of an instruction set 
architecture where someone was saying an instruction was required to 
test and set a bit or word as an atomic operation if it was desired to 
support multiple processors.  Is this really true?  Is this a function 
that can't be emulated with other operations including the disabling of 
interrupts?
