I think the right thing to do is something inbetween. If the connection
times out while the user is still filling the form, psi should add a small
red text to the form but keep going. If the user submits psi will reconnect
and send the data to the server. Yes, this is a bit "racy" but in the
normal case it works...
I bet server admins are not changing their setting all the time to annoy
users ;)
But it's not really any more racy than any normal http form processing.
