…19459) The tcp and unix input sources were leaking references causing a memory leak. When an accepted connection ended inputsource/common.Closer was supposed to delete the pointer that it held to the connection, but due to a code error `delete` was being called on the wrong map. Instead of modifying the common.Closer I replaced it with a cancellable context.Context which is designed to propagate signals from parent to children and requires less code. (cherry picked from commit 61f4846)
