While profiling scrolling in mailnews, I noticed an extremely large fan-out from
nsXBLBinding::GetBinding(). Specifically, ~1,000 calls to GetBinding() exploded
to about 20,000 calls to GetAttribute(), meaning that we are copying at least
twenty strings per binding.
FWIW, GetBinding() accounts for about 10-15% of the time spent scrolling in
mailnews (when scrolling in "new" content). If we can reduce the fan-out, we'll
pick up some percentage points...
