# ReadWriteLock

... A lock with shared/exclusive access modes, for the Raku language.

## Features

* Does what a basic `Lock` does, just slower and wit more bugs ;)
* Reentrant: the lock can be taken again by a thread that is already holding it
  It needs to be unlocked the same number of times it was locked before it can
  be taken by another thread
* Fair in the sense of first-come-first-serve
* Shared access: multiple 'readers' can share the lock, yet access is mutually
  exclusive between 'readers' and 'writers'

## Planned Features

* Finalize some design questions
* Proper POD6 docs
* Lock Upgrade Case
* Async version that returns threads to the threadpool and returns a promise
  from lock()
