image_tag()helper is a sucker for memory.
It takes more than 34 megabytes of memory to render a page displaying a list of about 500 rows, each accompanied by a set of four or five icons, each icon's
<img>tag created by
image_tag()helper, with additional parameters provided like this:
image_tag("some_image.png", "alt=Lovely, title=Rita")
With those images coded explicitly, rendering takes just 8.5MB. A leak, maybe?
