Lock

A lock shared by every thread and process on the cache: acquire(), release(), locked(),

Usage

Source

Lock(
    cache,
    key,
    expire=None,
    tag=None,
)

or with lock:. Not reentrant (see RLock); any holder of the key can release it.

acquire() polls every millisecond until it gets the lock. Give it an expire so a holder that dies without releasing doesn’t keep it forever.
