Comment:

 There seem to be two high-level ways to solve this issue:

 1. Reduce the timeout for dirport connection establishment to be very
 small.
 2. Ask k directory requests at once (perhaps until we start getting
 answers, then slow down).

 Are both good ideas, assuming we could do them right? Can we do the first
 easier as the second?

 Is some form of the second one already done? I swear I've seen my client
 do multiple tunneled dir conns in the Vidalia window and on the control
 port... If it is done, why does this bug still cause us problems? Is
 bootstrapping somehow different?
