Myk,
Thanks for your detailed answer. It's nice to know this will be in TT3, but
the future is not quite now, as you so enthusiastically stated, since TT3 is
still under development.
I'll check out your FLUSH directive when (actually, if) I have time, but I
would honestly prefer a less kludgey solution (no offense to your effort
intended). So for now I'll wait until TT3 is out.
