Ah - I see where the confusion is seeping in. I should never have
included Restart as one of the semaphores posted to the unikernel - I
simply meant a STOP-START sequence. Nothing to do with process control.

Erlang. For my own needs, though, unikernels are perfect - with the
addition of Lifecycle ;)
