Fix an issue caused by PR #10891: we introduced the concept of timeouts for heartbeats, where we would hang up on the other side of the oneshot channel if a timeout happened (future gets cancelled, receiver is dropped). This hang up would make the heartbeat task panic when it did obtain the response, as we unwrap the result of the result sending operation. The panic would lead to the heartbeat task panicing itself, which is then according to logs the last sign of life we of that process invocation. I'm not sure what brings down the process, in theory tokio [should continue](https://docs.rs/tokio/latest/tokio/runtime/enum.UnhandledPanic.html#variant.Ignore), but idk. Alternative to #10901.

Stuff is healthy again, so #10902 seems to have fixed it. Closing this as not needed. |
