title="ASSIGNED - WebAssembly: manage memory better"
href="show_bug.cgi?id=170628">bug #170628</a> 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.</pre>
