BTW a quick check would be to attach with gdb right after you connect,
check info threads (there should be none), run the plperlu procedure (with
the right arguments/calls to hit all the execution paths), check info
threads again. If info threads now reports a thread, we are likely looking
at the right plperlu code. It should just be a matter of commenting stuff
out to deduce what makes the thread. If not, it could be that plperlu is
not at fault and its something else like an extension or some other
procedure/pl.
