Update: Although the prioritization of specific cache entries increased the RSS significantly, the updated release logic presented here still seemed viable and offered a notable improvement to a thrashing problem in which consecutive releases could cause a high frequency of secondary cache scans. The new release logic, without the separation of committed and recommitted entries, is reintroduced in #107507.
