I was working on layout tests for Bug 9947, when I suddenly noticed that iframe
content was disappearing after I reloaded the layout test too many times.

Steps to reproduce:

1. Load test page.  Set "count" to 1.
2. Click reload browser button 29 more times (until "count" is 30).  Pause
between each reload until it is complete.

Expected results:

The same seven iframes should appear every time the page is reloaded.

Actual resutls:

On the 29th reload, the bottom three iframes disappear leaving only four
iframes.  On the 30th reload (and all subsequent reloads), all seven iframes
disappear.

Note that I haven't tried reloading much beyond 35 to see if they come back.

Regression:

Works as expected on production Safari 2.0.4 (419.3) on Mac OS X 10.4.7
(8J135/PowerPC).

Notes:

Tested on locally-built WebKit r15466 (debug build) with the above versions of
Safari and Mac OS X.
