Good point.

It *would* be really interesting to have some way to check our assumptions 
(both ways - warn about over-large inlines and small-and-hot non-inlines). 

I considered making sparse give some size estimate for inlines and warn 
about ones that generate a lot of code, but I was never able to do it 
sanely.
