  It would be fine if you could specify a max_trace_level for an object.
This way you could have a very high global max_trace_level and a glass
object with a smaller one. Like this:

global_settings { max_trace_level 20 }

object { WaterGlass max_trace_level 5 }

  This could mean that when a ray hits the WaterGlass object, it will be
reflected/refracted up to 5 times instead of 20 if the reflected/refracted
ray hits the same WaterGlass object again.
