Title: Don't accidentally step over and actually execute a side-effect-y instruction when emulating sigreturn.

Resolves #31. Was surprisingly hard to get the sysemu dance right, although the patch is extremely simple.

Last of the VM intermittent failures, leaving only very rare #401 on bare metal.
