Many thanks, Danilo -- that fixed it!

"rcapparmor stop" and "rcapparmor kill" did not help.  I had to 
add that kernel option and reboot.  The apparmor module is compiled 
into this kernel, but the option evidently deactivates it.

Dosemu actually ran a game!  Not any that I really want to run -- 
Apogee Crystal Caves, Secret Agent, and Cosmo.  But it's a start, 
and I can try various fixes, including modifying dosemu if I have to.
