These have identical behavior to interpreted executors, except that
they consume more memory for the generated machine code and are a lot faster.
## Transfering control
## Transferring control
There are three types of control transfer that we need to consider:
* Tier 1 to tier 2

#### The interpreter
The tier 2 interpreter has a variable `current_executor` which
points to the currently live executor. When transfering from executor
points to the currently live executor. When transferring from executor
`A` to executor `B` we do the following:

`A` is elevated by one)

#### In the JIT
Transfering control from one executor to another is done via tailcalls.
Transferring control from one executor to another is done via tailcalls.
The compiled executor should do the same, except that there is no local
variable `current_executor`.
