I said nothing about "reserved". I said "telling the system what you're
editing". When the system has to stat 20,000 files to figure out what
changed, that can take 10 minutes on typical Windows file systems. If
the system already has a list of the files that you have changed, because
you told the system, then it's instantaneous.

I am not advocating reserved check-outs. Indeed, I'm advocating something
which could (should!) be implemented solely using client-side state, to
greatly accelerate operations that need to know which files have been
changed.
