  Indeed the idea is nice...

  Launching a thread for this shouldn't be difficult, but IMO it would only
  be a speedup for the keys not in the local keyring, so you'd have to
  provide a way to know that before checking to decide to create a thread or
  just do it like now. This method can rely on gpg, but then it _may_ be as
  expensive as doing the proper check, hence you'd be slowing key checking
  of cached keys a lot. If you don't rely on gpg you'd have to implement some
  table of known keys, going into the nice problem of keeping the CM table
  in sync with gpg one, as gpg can be used by more applications than CM.
  Don't forget to make these threads cancellable, or, at least, able to
  discard their results, because when browsing summary view quickly the
  message view which launched the thread may not exist anymore...

  So, yes, best of two worlds is possible, but you have to depart from
  simplicity planet first ;-) Anyway, if your itch is big enough I'd love to
  test your patch, responsiveness would be much better for sure.

  IIRC gpg already does this in the public keyring, you probably need to
  launch a gpg --refresh-keys periodically to keep them up to date and go to
  the network only for the new ones.
