It seems to be the reflection 'exponent sqrt(2)'.  Note i also get 
occasional render freezes (i.e. the render halts and the program can 
only be stopped by multiple CTRL-Cs) in 3.6 when using the fresnel 
reflection.    Since i never had any problems with fresnel reflection 
before i assume this is something specific to this scene (i.e. the 
mesh).  Lowering max_trace_level strongly or not using radiosity avoids 
this (so maybe the ray recursion handling of radiosity in combination 
with reflection does not work properly although i have rendered a lot of 
scenes with radiosity + reflection without problems).
