That doesn't contain calls to sbrk at all, it maps memory in with mmap which is typical of every modern memory allocator.

It uses both brk/sbrk ("__brk()" in that code) and mmap, the latter for allocating larger bits of memory. GNU libc does the same thing from what I remember from straces.

You're right, I misinterpreted the calls to __brk
