So, it's not the network for me.
The imap server is gmail, so I think opening different connections should
allow all my folders to sync in // faster than doing them sequentially.

I'm however seeing // downloads being slower than a serialized download
right now, and I'm not sure if gmail or offlineimap is to blame.
