Forbidding writing to the root resource counter is a policy decision
I am unable to make up my mind about. It sounds right, but unless
we have a notion of unlimited resources, I am a bit concerned about
taking away this flexibility.

memparse(), makes it so much easier, we need to use it.

I like the read_uint() and write_uint() overall, but in the case
of setting the limit, I'd still like the flexibility of having
a strategy pattern that would make the UI more friendly.

Do read_uint() and write_uint(), just read and write unsigned
integers?
