plperl stashes the results in a tuplestore object, which spills to disk.
So memory use is not unbounded. Before 8.1 we had no return_next and no
intermediate tuplestore, so we had serious memory problems with
returning large sets.
As for SPI calls, we also had problems there but now we provide a cursor
interface that works much more nicely.
