sbrk

I would like to dynamically allocate memory from an assembly program that does not link against the standard C library. Since brk(2) and sbrk(2) are unavailable on Mac OS X (10.6.2), what are the alternatives?

(I'm guessing that it involves a Mach call, but there seems to be little documentation around that)
