I bet you've bumped into a bug in gist redo code, the cleanup phase
shouldn't take long. It's just for completing any incomplete splits by
inserting pointers to upper-level pages, and there shouldn't be more
than a few of those active at any point in time.

It looks like there's been quite a few changes to gistlog.c that haven't
been back-patched. This one in particular might be relevant here:
