# TODO: Remove the transport-based lock_read and lock_write methods. They'll

# then raise TransportNotPossible, which will break remote access to any

# formats which rely on OS-level locks. That should be fine as those formats

# are pretty old, but these combinations may have to be removed from the test

# suite. Those formats all date back to 0.7; so we should be able to remove

# these methods when we officially drop support for those formats.
