Thanks for the pointer, very helpful.

Anybody ever checked jemalloc, or any other OSS allocator out there 
against these patents?

Remembering similar patent-discussions, it might be better to not bother 
too much and just go with something widely used, based on the assumption 
that such a thing is going to enjoy broad support in case of an attack 
from a patent troll.

What do you think? What'd be your favorite allocator?
