+Signal dispatch has been moved from the runloop into control ops. This should
+give a few percent speed increase, and eliminates almost all of the speed
+penalty caused by the introduction of "safe signals" in 5.8.0. Signals should
+still be dispatched within the same statement as they were previously - if
+this is not the case, or it is possible to create uninterruptable loops, this
+is a bug, and reports are encouraged of how to recreate such issues.
