Stuck at blank screen after shutdown

[rakslice]

Shutting down the emulated mac is apparently detected by the emulator, as you don't get the default mac shutdown message with restart button, but it leaves you at a blank black screen with no apparent ui to restart or exit the app other than using a task switcher to kill it

It's only when network is configured.

Just starting to look into it in my local build, QuitEmulator() doesn't complete. We get into ExitAll() but it doesn't get past EtherExit().

It seems the problem is shutting down the slirp and main ethernet threads; android has pthread but no pthread_cancel() so the code doesn't cancel it but still joins waiting forever for it to somehow exit.
