[MEDIUM] fix broken redispatch option

Since the connection queueing was introduced, the "redispatch"
option could not cover the cases where a connection has been
refused by the server after having been marked "in progress".
The fix consists in doing a redispatch in the delayed connection
handling code.

Problem reported by Konrad Rzentarzewski.
