Well,  the bad news is I forgot to include the mmap.c patch :-(
I have attached the sys_brk inplementation.

I have been meaning to post a new patch,  but I am still working on a bug
in the binfmt_flat.c stuff,  which happens more easily with the new malloc.
There are a few bits of code that re-use memeory after they free it :-(

The sbrk stuff is fine though,  so you shouldn't see any issues with it.

Cheers,
Davidm
