Yep, Marius has already corrected my poor math.

I just want to point to the fact that such "solution" will introduce noticeable delay in some odd
cases, and so it should (?) be used very carefully. Leaving the temp file when bzr cannot remove it
is smaller evil for me. But... I don't have anti-virus scanning all my files all the time, so I can
miss something obvious and very important.
