Further bug fixes to the v5 WS

Joe has been pounding on the v5 WS trying to shake it out from the recent disaster with problems returning NVIDIA GPU WUs.  The upshot of all of this is that the v5 server code was pushed hard in many ways and several issues have now been found.  Joe is testing them, but we're hopefully that beyond the initial good news we had a few days ago, that several additional issues may now be fixed.

It's too early too tell since we're still testing, but I'm optimistic. This only affects particular servers (vsp07b, vspg10a, vsp11a) and the vsp09a CS.
