Claim ID
selection-async-protocol
Assertion
X11 selections are an asynchronous protocol: the owning application holds the data and responds to paste requests on demand rather than copying data to a central store. As a result, clipboard data disappears when the owning application exits, unless a clipboard manager is running.
