Fork?

If you save the forked PID in a session variable, you can then use the
meta refresh tag to revisit the process every, maybe 30 seconds, and when
the process is finished, do whatever cleanup you need.

          if (mod($z++,100)) {
              echo 'mailed some more';
          }

Dunno about that. You'd need output buffering turned off, at the least
(oh, I see that's where the flush come in, err, goes out.). Actually, I
don't off the top of my head know what the php modulo function is. But,
the browser'd be gettin' stuff, I think.

Well, decided to RTFM. ref.math.html doesn't list any modulo function.
Abitrary number base conversion -- yeah, got that, but you want the
remainder after division? Sorry bub.
