This depends on what your system has set for the tunable
/proc/sys/vm/mmap_min_addr. On my system it is 65536 (I think
Ubuntu and Debian ship like this), and in that case you can't
mmap MAP_FIXED to address zero unless you're root (tested with
a little C program that does the same mmap that runcom does).
