If it's not slow enough, you can always increase the value for
disp_nelems :-)


There is one change needed to the code.  It renders all refractive
media, whether dispersive or not,  as if they were dispersive.  If
dispersion (actually, ratio of dispersions of the two media)  is equal
to 1.0  (this being the ratio of red IOR to blue IOR) my code still does
a loop and traces fifty rays :-(  but insertion  a simple "if" statement
that tests for  dispersion being equal to 1.0 (within EPSILON)  can
solve that problem.  

I will post a patch eventually.  As soon as real life lets me.  (I wish
real life would render faster so I can play more often)
