Well, the original subject line of the report had mentioned SR only,
but I had a specific theory about what might be happening that was
related to the operation of HS. You've said that you think my guess
is incorrect, and that's very possible, but until we actually find and
fix the bug we're all just guessing. I wasn't intending to cast
aspersions on your code.
