And it's not going to. I'm not going to merge YASA that will stay around 
for years, not improve on anything, and will just mean that there are some 
bugs that developers don't see because they depend on some subtle 
interaction with the sl*b allocator.

We've got three. That's at least one too many. We're not adding any new 
ones until we've gotten rid of at least one old one.
