http://www.python.org/sf/1599254 is a bug in the mailbox.py module that affects single-file mailbox formats (mbox, Babyl, MMDF) and can cause data loss.
I can't speak for MMDF or Babyl, but it's a well-known requirement that all programs on a system must use the same type of locking when mbox files are used; the administrator picks his favourite (fcntl, dotlocking, whatever) and then has to ensure all mbox-aware programs are compiled to use that locking style.
A proposed fix, mailbox-unified-patch, is attached to the bug.
I'm not sure that this actually fixes the problem, but more to the point -- I'm not sure it should try. Any mail admin that deploys multiple mbox-aware programs with different locking methods is shooting themselves in the foot, regardless of whether Python tries to turn it into "just a flesh wound"...
