No, it is the other way around. On platforms that don't terminate between
each render you would get some unexpected results. This is fixed now and to
continue a render with radiosity will work a bit better now.

You can observe at least the max_trace_level bug in the Windows and Mac
version of 3.1a: Create a scene and set do not set max_trace_level in that
scene In the statistics output you see something like "Max Level: 2/5" where
the 5 is the max_trace_level. Now change it to to some value other than the
default (which is 5), i.e. use 20. The you will see "Max Level: 2/20". Now
remove the max_trace_level again and you would expect "Max Level: 2/5" but
get  "Max Level: 2/20". In 3.1d this is fixed and you get as expected "Max
Level: 2/5". (I am not sure, but I think you can't see radiosity_trace_level
problem anywhere in the stats output.)
