Well, we had a lengthy discussion on this in the German sub.sys.amiga
group. We came to the conclusion that it would really be dangerous!
Because, if your Amiga runs long enough and runs such programs in a
tight loop, the use counter of the library will be increased every time.
And, after *some* (:-) time, it will wrap around to zero. And, if it
happens that you have a tight memory situation just in this moment and
exec flushes all unused libs: POOF! I admit, not an everyday scenario, 
but sure possible :-).

You see, there was a related discussion whether you should check for
success of opening dos.library (or which lib was it?) at all, because
theoretically you always will succeed. But also there it was concluded
that you better use the safe way.
