Active development on vip_malloc() call stack. Right now, I am able to make the call to vip_malloc() from memallocator-vipzone, but the actual vip_mmap syscall fails in sYSVIPMALLOc(), defined in malloc/malloc.c. The vip_malloc() code is currently greatly simplified from the full version to avoid complications from binning and sbrk().
Simplified vip_malloc to just be a vip_mmap wrapper, as there is little utility in having a more complex scheme without a vip_sbrk() implementation for ViPZonE.
