Yes, thats the problem, the only thing you could do to prevent this is to hook
the etv_term vector, and wait for a keypress or something if the program was
not terminated normally.

Thats also the difference in EmuTOS: it displays the panic, then waits for a
keypress before terminating the program and returning to the desktop. If you
enter debugger at this point, symbols should still be there.

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.
