Yeah, this clearly needs more work.  xlogreader.c is difficult to work
with and I think we need to keep trying to improve it, but I made a
bad call here trying to combine this with other refactoring work up
against a deadline and I made some dumb mistakes.  I could of course
debug it in-tree, and I know that this has been an anticipated
feature.  Personally I think the right thing to do now is to revert it
and re-propose for 15 early in the cycle, supported with some better
testing infrastructure.
