    - `apiserver_flowcontrol_upper_limit_seats`: Configured upper bound on number of execution seats available to each priority level
    - `apiserver_flowcontrol_demand_seats`: Observations, at the end of every nanosecond, of (the number of seats each priority level could use) / (nominal number of seats for that level)

<code>~[]E</code>. This can be expressed as <code>S ≡<sub>C</sub> ~[]E</code>
where <code>X ≡<sub>C</sub> Y</code> stands for
"<code>X</code> satisfies constraint <code>Y</code>".
These observations lead to a set of two equations

and <i>w'</i> happens before <i>r</i>.
That is, each read must observe a value written by a preceding or concurrent write.

<p>
Additionally, observation of acausal and “out of thin air” writes is disallowed.

Reads of memory locations larger than a single machine word
are encouraged but not required to meet the same semantics
