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.. :)
