*
* Note `SIG_DFL` still results in process death for most signals.
*
* POSIX defines raise() errors as returning non-zero and makes setting
* `errno` optional. Every platform we've tested in our support vector
* returns -1 with `errno` on error (like a normal system call).
*
* @param sig can be SIGALRM, SIGINT, SIGTERM, SIGKILL, etc.
* @return 0 on success, or nonzero on failure
* @return 0 on success, or -1 w/ errno
* @raise EINVAL if `sig` is invalid
