   Well, builtin is the default name for compiler um.. well.. builtins. 
   It's been around for a while.

uh, i mean, we define predict_true() to make use of this feature :-)
   
   Unless you meant the name that Frank chose, yeah, it could be better. 
   Personally, I like expect as a name for it, tells you what you are
   telling the compiler to expect to happen.

i don't really care much either way, but "UNLIKELY" is very ugly to me.
