Hmm culicidae still fails, this time only in parallel worker code. This
didn't happen on my machine which is strange. Looking at the code, we
are passing the fps->entrypoint as function pointer again so of course
it fails. We have some code to load libraries again but even that gets
initial entrypoint passed as function pointer
(ParallelExtensionTrampoline). I wonder if we'll have to generalize the
InternalBGWorkers even more to some kind of internal function name to
pointer map and add the parallel entry points there as well.
