Details

This finalizer is a non-trivial portion of foreground finalization work in some cases.

eg. http://arewesmoothyet.com/?category=all&durationSpec=128_512&mode=explore&payloadID=cc272d3263f6417891ac38dda1ec3ef7&search=FinalizeArenas&thread=0&transforms=ff-5020

We should investigate making this background finalizable. There is a bit of existing cleverness with the source compression tasks and the incremental-xdr (which will be removed in Bug 1586771), but it may be possible to solve these.

One of the remaining this is an embedding hook which might make this less possible.
