-// This test verifies a real bug I hit developing the vector-of-sequences

-//
-// Clients would see something like
-// * In the original stream, Cfoo=5,Cbar=8
-// * In the resumed stream, Cfoo=6 (no Cbar sequence number)
-//
-// Disconnecting and reconnecting a second time, using event IDs from that
-// initial period of the first resume attempt, would then cause the second
-// resume attempt to restart all other channels from the beginning, and not
-// from where the first disconnection happened.
