There's support in PostgreSQL to drop "interrupt-me-now-if-needed"
statements in the extensions code. Unfortunately the union operation
is all happening within GEOS so there's no way for use to play
with that interruption thing.

ST_MemUnion calls Union multiple times, so you can kill it between calls.
