I believe Electric fence's malloc doesnt use fenceposts like the libc's 
malloc, so I doubt this is the issue.
Each allocation gets its own page surrounded by two unmapped pages, so 
it is impossible to walk
to any other allocated memory without hitting an unmapped page first.

I can't use valgrind on this code because it doesnt support the needed 
system calls yet.
