Callback with redirect breaks lifecycle of page

[stever]

Callback with redirect breaks lifecycle of page -- it acts like it is a non-callback (which needs to end the page so it can add a header and exit).

However, in this case the callback gets shutdown before it is supposed to. On all our machines this has the effect of calling the callback twice (I think it is an error with php 5.2 on the twice part).

The fix here fixed it up perfect.
