Sure, I agree.
I think when we access only global variables in the condition and those 
variables are not changed in the probe point, the probe will be disabled
automagically from other probes where those global variables are changed.
And This optimization depends on where the global variables are changed.
Procfs probes and timer probe are good places to do that.
