I have pretty good skeleton for TSR program, although I haven't used it in
Arachne package yet. It includes loading, detection of being already
loaded, safe unloading, installing API on some interrupt, and testing DOS
busy flag.... pars of code came from various sources....
I can LGPL it and put on gnu.arachne.cz..... or I will send it to Bernie,
and Bernie can do it...
