I was thinking of something more agressive:

if target (via /proc) can identify exec file
	switch to target's exec file, load
else if exec file known
	load
else
	hope the user knows what they are doing
fi

which is different to the current logic like:

if exec file known
	do nothing
else if target (via /proc) can identify exec file
	switch to target's exec file, load
else
	hope ...
fi

however yes, at least (per your patch) always loading the symbols is a 
good first step.

(this goes back to earlier posts where we need to overaul the target 
stack so that multiple instances are available)
