Exiting with a signal should not be treated the same as successful exit with zero status. Return signal exit information to the callers via negative integers, to enable distinction from normal exit statuses. (All consumers that check for errors don't care what the exact non-zero exit value is -- in such a case they print a diagnostic message and either continue or bail.) Additionally, check for unexpected sources of waitpid() wakeup and bail if we encounter them.

FreeBSD
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
