no credit is due to me.

the filesystem hit is not really a function of processor speed. creating
a new file involves lots of logic and synchronization with other things
that are accessing the filesystem, and although its probably faster on a
3GHz Core 2 Extreme than a 100MHz Pentium, the difference is not likely
to be anywhere close to a factor of 3000.

in all likelihood, i've just been overconservative when worrying about.
the chances are that we could open a new file on every loop and it would
be fine. so far, though, my conservatism and concern about burning
needless CPU cycles and causing slowdowns with synchronization seem to
have benefitted ardour quite well compared to some other DAWs.
