I haven't tried that before, but I would be concerned about the ability to
iterate cleanly in the presence of concurrent changes.

I had hoped boost filesystem uses a replaceable back-end so I could target
it against other filesystem providers (other than POSIX, Win32), but I
don't see that architecture internally.  :(  Would be nice to have a
complete back-end abstraction so one could provide their own.
