Not sure, but it should work if the sole issue is that the realtime process is
sitting in a busy loop.  Note that if the machine is inaccessible for other
reasons, like a kernel oops, then astcanary can do nothing about that.

Note that a Linux machine being pingable says nothing about the status
of the kernel.  A Linux machine will still reply to pings, even with the
kernel halted -- it's one of the rather strange behaviors peculiar to that
kernel.
