I think the easiest and safest thing to do now is to just prevent
parallel plans in the walsender.  See attached patch.  This prevents the
hang in the select_parallel tests run under your new test setup.

Unifying the signal handling and query processing further seems like a
good idea, but the patches are pretty involved, so I suggest to put them
into the next commit fest.
