Comment (by pramsey):

 Hm, so maybe this is not to do with the GEOS interrupt at all, but more to
 do with the kinds of interrupt we're working with at the PostGIS layer. I
 *think* that restart sends kind of a "gentle interrupt", perhaps the issue
 is that we only respond to a harder one (whatever the analogue to a ctrl-C
 in psql is). I did find interrupt handling code in GEOS in the main noding
 routines, so it's unlikely to wait very long to hit a handler.
