Wave Link 3: the autorelease pool grows without limit on an audio worker thread

Summary

Wave Link 3.2.2 increases its memory footprint continuously. We observed no bound. The process ran for 5.9 days. Its physical footprint reached 3005 MiB. 2724 MiB, or 90.7%, of that footprint holds autorelease pool pages. Those pages hold pointers and pool boundary markers. They are not object allocations.

The process owns 697,437 AutoreleasePoolPage allocations. Each page is 4096
