Upstream: avoid holding a cache node with upgraded connections. Holding a cache node lock doesn't make sense as we can't use caching anyway, and results in "ignore long locked inactive cache entry" alerts if a node is locked for a long time. The same is done for unbuffered connections, as they can be alive for a long time as well.
