Uh, how's that OK?  There's no rule that you can't create a
ParallelContext in a worker.  Parallel query currently doesn't, so it
probably won't happen, but burying an assertion to that effect in the
predicate locking code doesn't seem nice.

Is "sxact" really the best (i.e. clearest) name we can come up with
for the lock tranche?
