Thanks, Juergen. My current hypothesis is that there is some sort of buffering issue with the ASP or SP system. I'm at a bit of a loss as I don't actually have a system that can reproduce the behavior, so it's hard to investigate. I'll stand by until you or Chris can get back with a test of the latest git (rc3), which might fix the issue by shrinking the write buffer.
