Comment (by nacin):

 I'm not comfortable loading 30.3MB -- with server configurations and a few
 plugins, that goes above 32MB very easily. We either need a second layer
 of caching to avoid loading SimplePie on the dashboard, or we need to ask
 for more memory on the dashboard.

 I don't know which is easier. Second layer of caching might not be
 difficult to bake into the widget caching function, but I also know that
 trying to add transient caching drove both Mark and I mad initially.

 Asking for more memory is easy, but that's actually uncharted territory.
 We currently only bump the memory limit to WP_MEMORY_LIMIT or
 WP_MAX_MEMORY_LIMIT -- we want something in between, which means we need
 to check it against both of those constants. Given the pedanticism in
 #14889, introducing a middle-ground, hard-coded value of, say, 48MB might
 mean we need to revisit our memory comparison handling.
