Chris and I have also tried viewing the full braidwood geometry with
HEPREP without any success. Opening a file with one event and all
1200 PMTs enabled in JAS3 brought an Opteron with 1GB of memory to
its knees before I finally killed the program. I haven't dug in any
further, but I wonder if there is some problem in the way it stores
the PMT models, since those have been implemented as using a custom
geometric object.
