A topic that I'd find interesting is what it'd take to make it easier to
use profile guided optimization in the context of JIT.  A few years back
I crudely hacked this together, but it was fairly ugly. It'd be nice to
make that easier.  Possibly too complicated for that type of session?

I dimly recall that the main issue was that there is no good way to
extract the profile information without going through files / applying
the profile data without going through files.
