Balaji,

1. Since the command stack's purpose is to support undo, limiting the size of
the stack will limit the otherwise unlimited undo. Of course, there's no such
thing as unlimited - as you point out, at some point memory will run out.

2. Commit, would be a great point in time to flush the command stack, since as
you say, undo is no longer possible in the backend anyway.

Frank.
