--- Comment #1 from Chris Dumez <cdumez at apple.com> ---
I have just discussed this with a RunningBoard engineer. The most likely explanation is that the pid is < 0 (which is possible since pid_t is an int on our Darwin). We get the pid from xpc_connection_get_pid() and I guess this could theoretically return a negative PID (maybe in case of error when the process has already exited).

I think we should tweak the PID check on WebKit side to early return if pid <= 0 (instead of doing an early return when !pid).

Are you able to write up the patch?
