My fault there - stupid mistake.

I'll return with some actual data so that others can get a better
picture of what we're seeing. I'll also see if I can come up with a
way to reproduce the issue on a smaller configuration; might not be
possible, but attempting to do so might provide some more insight into
our problem.

Thanks for your detailed description of the code path! I definitely
understand that our assumption can't be the actual problem here. I'll
dig back into the issue and try to get some better information.

Thanks again!

- Alex
