The MemShrink project  has been around for several years. You may have seen the [MemShrink] tag added to bugs and then later on given a priority of P1, P2, or P3. This was the product of weekly (and then bi-weekly) video meetings held to triage these unprioritized bugs and discuss all things memory.
We would like to move to a more asynchronous, open, and inclusive system. To support this goal a new mailing list, dev-memory , has been created where we will have a weekly triage discussion. All other memory related topics are welcome as well.
For all interested please sign up for the list , add a [MemShrink] tag to memory related bugs you see, participate in the triage discussion, and post to the list about memory related topics and concerns.
