Bug ID: 170773
Summary: WebAssembly: free cached fast memories if they go
unused for a while
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: JavaScriptCore
Assignee: webkit-unassigned at lists.webkit.org

Depends on: 170628
Blocks: 159775
As of bug #170628 the GC knows some things about WebAssembly fast memories. Maybe it should know a bit more, and free up unused fast memories if they seem easy to get but haven't been getting much use recently.
This is at odds with pre-allocation to avoid fragmentation, so we have to be careful.
