However it is also important to realise that malloc and free are not system calls. This is important because while brk/anon-mmap are relatively expensive, malloc and free are signifigantly cheaper. In most cases you are better off tuning your allocator then avoiding dynamic allocation.

Significantly cheaper, yes, but still expensive from some perspectives. A lot of my recent coding has been done with OpenGL, and I anticipate a point in the future where allocations will be the major bottleneck. It may be farther off than I think, of course, and I'll wait till then to optimize... but it's still a fun thing to know how to do!
