kernel - Fix long-standing vfork/exec bug

* Fix an issue where the parent process can get stuck in the "ppwait"
  state due to a tsleep/wakeup race with its child.

* This bug was present but masked by other tokens prior to a few patches
  ago.  With those tokens now gone this bug reared its face.
