hrm... it used to never fail.. that may have changed. But it will definitely block and try very hard to push things out to make space, which is the whole point :-) > I will have to add that back as there is no more fallback. Well, the must be one in the case the tree isn't initialized yet, so if there's an allocation failure, you may "de-initialize" it or something... Or you can fallback if you don't find, as easy, probably easier since it shouldn't happen in practice. > > I don't know if it's worth trying to fire off a new > > allocation attempt later, probably not. > > I've been pondering with this lately, but I think that adding a linear > lookup fallback should be OK.
