Overcommit can be used for many reasons. I use it to reserve a large
linear address space to mmap alpha i/o spaces to which allows an efficient
implementation of inx/outx in user mode:
UID PID PPID CPU PRI NI VSZ RSS WCHAN STAT TT TIME COMMAND
0 43655 43652 7 2 0 12616584 12456 select S ?? 1036:41.62
/usr/X11R6/bin/X -auth /usr/X11R6/lib/X11/xdm/authdir/A:0-w43652
The X server is using 12G of address space..
