Original GitHub issue: https://github.com/hickory-dns/hickory-dns/issues/971

Describe the bug
I am running the global_resolver example on Linux and Mac, both failed.

To Reproduce
$ cargo run --example global_resolver

Expected behavior
Print the valid socket address for the hosts.

System:
Mac and Linux

Version:
Crate: resolver
Version: 0.18.0 Dec 22, 2019

Additional context
Here is the output:

www.google.com resolved to Err(Custom { kind: AddrNotAvailable, error: "dns resolution error: proto error" })
www.reddit.com resolved to Err(Custom { kind: AddrNotAvailable, error: "dns resolution error: proto error" })
...

It fails here
https://github.com/bluejekyll/trust-dns/blob/master/crates/proto/src/xfer/mod.rs#L240
I see this trace. "unable to enqueue message".
I believe it's broken with the Background with generic spawn.
