Comment 29 for bug 397739

This is is a nice speedup, but not a low-risk bugfix that we could put into an SRU. Given Natty is now in alpha freeze (iirc) and might get this uploaded before beta, I think it's arguably safe enough for 2.3 if we're sure it's safe in trunk, and if the lp stacking issues are addressed first. Otherwise, wontfix for 2.3.
