No, if you were me, then you wouldn't :-P

A high count is vital, as the light coming through the keyhole otherwise 
creates a "disco ball" effect, i.e. bright splotches scattered across 
the room, and the light from the slightly opened door would form streaks 
on the ground. Been there, seen that. Reducing the error_bound would not 
be sufficient to fix that (and create even more samples anyway, which 
not only means again more rays to shoot, but also more samples to look up).

And increasing pretrace_start isn't likely to change a thing - not at 
these *_reuse settings, which mandate the sample density to roughly 
match pixel size (at a resolution of 1200x900 pixels).
