I think you misread it. Note the "n > 0" part of the while condition.
Current HaveNFreeProcs() iterates through the entire freeProcs list
(while holding ProcStructLock) just to determine if there's a small
number (superuser_reserved_connections) of free slots available. For the
common case, presumably it'd be faster to put the n<=0 test inside the
loop and return
