I see the problem, but consider mroe theoretical than practical. I think
it has been in blame for a long time (it was there before I started
messing that code up last spring at least).
I may look at it sometimes if no one else beats me. Maybe you should file
an issue.
BTW, the reason for closing the file "in case" is that it has to be closed
before deleted and the cleanups will do it in reverse order. This code
path is used if an error occurs.
