Comment (by boonebgorges):

 [attachment:6853.2.diff] is an updated patch, after the moves in #6870. I
 made the necessary additions to `$irregular_map`, and wrapped all new
 `require` statements in a `do_autoload` check.

 Rough benchmarks are showing a pretty consistent memory savings of between
 1.5 and 2MB, on a local dev installation that has about a zillion plugins
 running. On a front-end load, memory usage goes from just under 50MB to
 just over 48MB. If we assume that, say, half of that 50MB is directly
 attributable to BuddyPress, then we're reducing BP's memory footprint by 7
 or 8 percent with autoloading. And with some further rearrangement in the
 future (so that components are loaded in a sleeker way) we could get that
 number down even further.

 Comments and feedback are welcome on the technique used. And if anyone
 sees any gotchas that I'm missing, please speak up. It'd be nifty to put
 sneak this into 2.5.
