There's no such thing as a lock free malloc() that calls brk(), unless I
am confused.  brk() is a syscall that can block the caller.

To make a lock-free malloc(), you have to malloc() a big chunk of memory,
then run your own allocator against it.  You don't reduce your overhead at
all.

Or am I confused?  Allocators never were my focus.. :)
