Sequester Announce

Sequester is a writer preferred read/write lock for concurrent evented operations. I've extracted it from Strata where it's used to guard the b-tree pages.

This read/write lock allows many different "threads" of execution to use a resource in parallel, but when it is time to write, all readers will wait on a single writing "thread." The writing "thread" will wait until all outstanding readers release their lock before it writes.

This minimal concurrency primitive can be used implement standard semaphores if you only ever call exclude, read/write locks, and latches if you start of holding exclude.
