[ZendTo] Re: Release 3.64 with upload progress bars

I've just done an upload test with an 8.37GB file using Safari, and it
worked okay except the progress bar jumped backwards a couple of times
due to integer wrap in the APC C code.
So I've added "backwards jump protection" to the progress bar code,
which is attached. Just drop in this file in place of your current one,
and add 1 line to the PHP ini file that has your "apc...." settings in it:
apc.slam_defense = off
and then restart Apache/httpd.
IE9 did it well enough (same behaviour as Safari) too.
In IE8 the progress bar never moved off 100, and the browser timed out
(with a 3GB file) :-(
With a smaller file, it worked fine. Looks like IE has some problems
(again).
