Since in locking-based implementations it's going to be relatively easy to get
into a situation where readers starve writers when working concurrently, we
should have a note in the transactions section that encourages implementations
to have explicit mechanisms to avoid starvation. We don't want to be too
prescriptive, perhaps simply this statement:

"UAs need to ensure a reasonable level of fairness across readers and writers
to prevent starvation."

For reference, we discussed this here:
