synopsis: A thread-safe cache for sharing resources across threads with automatic expiry
description: A cache designed for guaranteeing that different threads can share the same reference to a resource. For example, it allows threads to communicate via a shared
<<https://hackage.haskell.org/package/stm-2.5.3.1/docs/Control-Concurrent-STM-TChan.html TChan broadcast channel>>.
Using <<https://hackage.haskell.org/package/resourcet resourcet>>, items are only removed from the cache after no 'sharers' are holding the
resource and the item has expired (according to the expiry configuration the cache was constructed with.)
.
Note: an MVar is used to coordinate between threads that only one thread does the initial load of the resource with the given IO action if multiple
threads try and retrieve a resource that is not yet cached at the same time.
