Which is why I suggest that by default symbols are never flushed 
automatically : you flush them if the user explicitely ask to do it or 
if another prg is loaded ; but apart from these cases, I think symbols 
should remain loaded.

Also, not all people are coders aware of gem/tos variables to hook such 
or such event ; demo coders are often used to code the "bare metal", 
basically going to supervisor mode and then don't use the OS anymore, 
just acces the HW directly.
