The problem is that there's a pin on an index page when the smgr tries
to drop its buffers. This patch corrects this problem, by having
resowner cleanup before smgr.

It also passes regression tests. Not sure if it's the correct solution
though, but it seems the natural thing to me.

Thanks for the report. I wonder how we managed to miss this.
