John Reiser 9e8de4abe5 i386: new stub strategy to avoid problems with early mmap layout 
The stub occupies the same region that execve() would create
for the original progam.  The stub copies everything to a new area,
erases the original region, replaces it with the de-compressed
program, and erases the copy of itself via the escape hatch.
The copy is inexpensive via mmap() of /proc/self/exe.
