| 13 | When an image is preloaded in javascript, the size of the image is never |
| 14 | reported to the javascript garbage collector. If a large image is repeatedly |
| 15 | preloaded but never used, it will not free any of the images until the |
| 16 | garbage collector has run out of space to allocate any new free javascript |
| 17 | variables. This test passes if after a certain point, the number of allocated |
| 18 | images as reported by the caches window stops growing. |
