An illustration of how bad the DOM memory regression is

[Steven Bosscher]

Hi,

DOM at work on the test case for PR15524 cut off after case 15000
(ie. the original test case but halved) on an AMD64 box with 3GB
of RAM:

{GC 9944k -> 8041k} {GC 2291229k -> 14365k}

The full test case sends the machine to swapping land.
Just gross.

Gr.
