TitleAWL does not recycle memory to the arena.
Assigned userGareth Rees
DescriptionAWL does not recycle memory to the arena.

An AWL pool will recycle memory but it only makes that memory available to the same pool. What it should do is return any memory that it can to the arena so that it can be reused by any pool.
AnalysisThis is a kind of deliberate feature of the design. Doesn't mean it's a good thing though.

Currently AWL doesn't easily know when a segment is entirely free and can therefore be returned to the arena, though I see no particular reason why AWLReclaim couldn't do this.
