Subject: Future: better doc + restore ~pure optimization

This optimization was undone because the kernel type checking was
not a pure functions (it was accessing the conv_oracle state imperatively).
Now that the conv_oracle state is part of env, the optimization can be
restored.  This was the cause of the increase in memory consumption, since
it was forcing to keep a copy of the system state for every proof, even the
ones that are not delayed/delegated to slaves.
