Added QMAGIC, which is a "compact demand load" format:  first page is
unmapped, and the a.out header is inside the text section.

From: Guido van Rooij <guido@gvr.win.tue.nl>

when mmapping a file, permissions are checked as it should be. When
mprotect()-ing the address range afterwards, no protection was checked
regarding the protection of the file originally opened. So
when you open /usr/bin/su RDONLY and SHARED you could afterwards change
the mmapped region to READ|WRITE. This gave the possibility to obtain
root privs obviously.

change from make tinguely (tinguely@hookie.cs.ndsu.NoDak.edu) to make
opening running programs for writing return ETXTBUSY.
