OK, thanks.  I committed that patch, after first running 100 million
tuples through a Gather over and over again to test for leaks.
Hopefully I haven't missed anything here, but it looks like it's
solid.  Here once again are the remaining patches.  While the
already-committed patches are nice, these two are the ones that
actually produced big improvements in my testing, so it would be good
to move them along.  Any reviews appreciated.
