This is not critical. It's just debug. When DEBUG_CALLS (or something
like that) is active, it will print "leaving function ... ". 

Indeed if it's missing, you might start to think why DID it return,
but not print the message... or. howcome it's still in that function
doing stuff that isn't there. Anyway, looking into it would provide
you more info that it was returning the error.....

Anyway, nice to clean it up "while we're at it".
