I hereby propose the creation of Project Loom with myself as the Lead and the 
HotSpot Group as the sponsoring Group.

In accordance with the OpenJDK guidelines [1], this project will provide a 
venue to explore and incubate Java VM features and APIs built on top of them 
for the implementation of lightweight user-mode threads (fibers), delimited 
continuations (of some form), and related features, such as explicit 
tail-call [2].

The initial Reviewers and Committers will be: 

* John Rose
* Karen Kinnear
* Alan Bateman
* Brian Goetz
* Mark Reinhold
* Ron Pressler
* Paul Sandoz
* Frederic Parain
* Erik Duveblad
* Vladimir Ivanov

The initial source of this project will be a clone of a JDK 10 repository. 
Changes from the JDK 10 parent will be synced into Loom periodically. Similar 
to Project Valhalla, we will follow a "commit first, review later" policy, as 
code will not flow directly from the Loom repositories into the JDK 
repositories, but instead will be done by a "curated merge" where select 
changes are extracted into new changesets for incorporation into JDK 
repositories when they are ready for inclusion. 

Votes are due by by the end of November 10, 2017 (UTC).

Only current OpenJDK Members [3] are eligible to vote on this 
motion. Votes must be cast in the open on the discuss list. 
Replying to this message is sufficient if your mail program 
honors the Reply-To header. 

For Lazy Consensus voting instructions, see [4].
