Once files are added (or removed or moved), need to send those changes to
all the other git clones, at both the git level and the key/value level.
## action items
## immediate action items
* Check that download transfer triggering code works (when a symlink appears
and the remote does *not* upload to us.
* Investigate why transfers seem to block other git-annex assistant work.
* At startup, and possibly periodically, look for files we have that
location tracking indicates remotes do not, and enqueue Uploads for
them. Also, enqueue Downloads for any files we're missing.
* Find a way to probe available outgoing bandwidth, to throttle so
we don't bufferbloat the network to death.
* git-annex needs a simple speed control knob, which can be plumbed
through to, at least, rsync. A good job for an hour in an
airport somewhere.
* file transfer processes are not waited for, contain the zombies.
* The TransferWatcher does not notice ongoing transfers, because inotify is
waiting for the info file to be closed, but that never happens, it's left
open to keep it locked.
## longer-term TODO
* git-annex needs a simple speed control knob, which can be plumbed
through to, at least, rsync. A good job for an hour in an
airport somewhere.
* Find a way to probe available outgoing bandwidth, to throttle so
we don't bufferbloat the network to death.
* Investigate the XMPP approach like dvcs-autosync does, or other ways of
signaling a change out of band.
* Add a hook, so when there's a change to sync, a program can be run
