`deno repl` hangs without network access

[mhio]

Running the repl in 1.25.4 and 1.26.2 in a debian:11 container hangs when there's no network access.

There are connection attempts to deno.land / tcp / 443, that seem to do a retry backoff which takes a couple of minutes

$ date; docker run -ti me/deno /deno repl --eval 'console.log(new Date())'

Deno 1.25.4
exit using ctrl+d or close()

I think it might be related to the connections being dropped rather than getting an ICMP response.

The --no-remote options don't seem to affect whatever is loading.

Could the remote lookups be disabled optionally? Is there a way to pre cache the remote lookup?

Is it the completions that are trying to load?

@dsherret should we add a timeout here and continue if completion setting can't be obtained?

I cannot reproduce this anymore; @mhio is this still happening?
