Same for running valgrind on DRT. This is on my shiny Lion iMac.
Can't use DRT anymore.

I've verified through manual printf() that it enters DumpRenderTree main(), but it stops after we initialized the NSURLCache, at some point, when its thread fires and tries to open the sqlite3 database, it just crashes. No idea why.
