Yup, that's the whole point of it.

Yes, without merge tracking;) Note that the problem would exist
anyway (without merge tracking) because files could be merged before
the conflict was detected.

It would be possible to scan all files/dirs for conflicts, but I think
that's a bit restrictive and I don't want to introduce this whole-tree
scan (even if it is in memory) for this case that should be rather
uncommon.

To scan only affected files before merging would mean that we have to
delay any merging until all diff data is received from the RA layer
witch hurts streaminess.
