Start by reviewing mailbox-unified.patch, mailbox-unified2-test.diff, and the later mailbox-tests-2.7 patches, then run the mailbox tests they modify or reference. Done means the reported concurrent single-file mailbox scenario no longer allows other programs' messages to disappear, with regression coverage preserved.
