Hey Maskim,

Looks good, thanks!

The test creates two veneers, one for reaching foo and another for start.
And we have three uses: foo -> _start, and vice versa, and hot -> foo.

As an optional nit, we could mention this in the test description, optionally make `_start` hot to check the replacement there too, or drop `_start` and its callers to simplify.
