Lieer writes to database continuously while syncing, which is bad on COW filesystems #309
Description
I'm doing the initial sync of my 6GB Gmail account with roughly 512k messages, and it slows to an absolute crawl, all while spamming roughly 40MB/s worth of writes nonstop to the database.
It would be nice if this could be collected as an atomic operation.
As an alternative, the user could use a tmpfs storage for the maildir until the initial sync is done.
