127	Opening 1jj2 pdb format is slow	Tom Goddard	Eric Pettersen	"Opening 1jj2 in pdb format takes 6 seconds, while  a 3 week old (July 15) Chimera 2 it opens and displays in 2 seconds.  Also opening mmCIF 1jj2 in the current Chimera 2 takes only about 1 second.

Timing statements show that the atoms.radii call in structure.py is taking 3.5 seconds for pdb format 1jj2 and only 0.15 seconds for mmCIF.  So part of the slow open seems to be atom radius computation.
