My guess is that positive values more often might have a meaning ("5
items changed", "address 0x1234") whereas negative values less often
have a meaning. Also passing -1 as parameter is more often invalid. Thus
passing -1 is making debug output look more suspicious.
(while there are cases where -1 is valid, see recent famous pid
= fork(); /* ... */ kill(pid, SIGKILL); issue)
