It depends. If B knows about A's change they probably would have expected
to get it. If they are relying on what Subclipse is showing them, then
they would probably expect to get the revision they see.

In the current software, B would not be able to commit because when they
did their update they did not receive A's change and would be out of date.
As for your question, if you do an update on a dir you have to be assuming
that you are doing it with the expectation of getting any changes within
that directory.

That isn't necessary. If file A is at revision 100, and B is at revision
90, then updating them both to revision 100 is the safe thing to do. The
way they view works, B could not have been changed between 90 and 100.

Not even remotely possible,
