Hi,

Commit 2207f73 changes the substituter to provide feedback when
hydra.gnu.org is unresponsive, which happens from time to time (the Nix
folks did a similar trick recently.)

If an HTTP GET hasn=E2=80=99t completed after 3 seconds, it prints a message
saying that the server is unresponsive and hinting at --no-substitutes.

This is better than having =E2=80=98guix build=E2=80=99 or =E2=80=98guix pa=
ckage=E2=80=99 sit here
without saying a word of what=E2=80=99s going on.

Comments and tests welcome, esp. from Guile 2.0.5 users!

Ludo=E2=80=99.
