Cannot get a grant for the full capacity

[szszoke]

I don't seem to be able to get a grant for the full capacity of my queue. The code below panics with InsufficientSize. I am running version 0.7.0.

use bbqueue::nicknames::Churrasco;

fn main() {
    let queue = Churrasco::<1024>::new();

    let prod = queue.framed_producer();

    let mut _g = prod.grant(1024).unwrap();
}

Something also seems to be weird when grants have been committed and released a few times.

use bbqueue::nicknames::Churrasco;

fn main() {
    let queue = Churrasco::<1024>::new();

    let prod = queue.framed_producer();
    let cons = queue.framed_consumer();

    for i in 1..3 {
        println!("Iteration {}", i);
        let mut g = prod.grant(1022).unwrap();

        g[0] = 1;
        g[1] = 2;

        g.commit(2);

        cons.read().unwrap().release();
    }
}

The code above produces this output:

Iteration 1
Iteration 2
