Yeah, I realize all that. It was a temporary step. In php.ini it’s 128m and it’s been fine. This just helped me figure out where the problem lay if not how to solve it.

Oops. Trying again:

/**
* In WP 3.5+, get_blogs_of_user() is much slower than in previous versions. As
* a result, if you have a certain number of blogs, running get_blogs_of_user()
* will create a memory timeout. This is a particular problem because
* get_blogs_of_user() is called on every page, because of the toolbar.
*
* Ideally, there would be a way to short-circuit get_blogs_of_user(), or even
* to prevent WordPress from calling get_blogs_of_user() while loading the
* toolbar. But there is not. As a workaround, this function intercepts a key
* step in get_blogs_of_user() – the get_user_meta() call that gets all of a
* user’s metadata. If we determine that this request is coming from
* get_blogs_of_user() (which we do by examining the debug_backtrace(), a truly
* awful technique), AND that it’s one of the generic meta queries used by
* get_blogs_of_user(), AND that the current user has more than 75 blogs, THEN
* we strip all of the blog capability keys from the array of metadata,
* tricking get_blogs_of_user() into thinking that the current user has no
* blogs at all.
