Sometimes yield_from_svc won't stop the emulator immediately #5

Closed dogtopus closed 6 months ago

This caused the emulator to continue executing until hitting the adjacent SVC instruction, triggering yield_from_svc again with that adjacent SVC and eventually causing the wrong syscall handler to be called.

Might be a race condition within Unicorn.
