It has nothing to do with "knowing" anything. It has to do with the
environment in which the code calling the exit runs, and avoiding
crippling the system by doing something differently that would likely have
horrendous performance characteristcs..

Oh - the BPX ptrace facility provides this function, there
is a ptrace event when another module is loaded...
And - that facility does not require any special priviledge (you're not
in supervisor-state just to use BPX ptrace.)
Does that mean performance is not an issue in that case?
It might be nice to have a similar facility for monitoring/debugging
that didn't require supervisor state and also didn't cause a image
to be dub'd...
