Networking process on iOS can be suspended and never exit

This is for apps that use multiple WKProcessPools and sometimes deallocate a WKProcessPool that had an active Networking process.

In those cases, the Networking process can be suspended instead of terminated, and once suspended it can no longer respond to further messages.

Furthermore, calling RunLoop::main().stop() is not aggressive enough to actually terminate the process - _exit is bulletproof.
