Example failure:
fRefCnt was 3
../../../usr/local/google/home/mtklein/skia/include/core/SkRefCnt.h:40: failed assertion "(fRefCnt == 1) || (SkDebugf("fRefCnt was %d""\n", fRefCnt), false)"
Command terminated by signal 11
Not pretty, but everything's there. Perhaps we'll think of ways to make it nicer later.
