Careful.  Estimate timeout is per client, not per disklist entry, and
is (etimeout * number_of_disklist_entries).  So if you have a client
box1, and box1 has three disklist entries, then the real wall-clock
estimate timeout for box1 would be 300*3 = 15 minutes

2.2 megs/second is *taper* throughput, not *dumper* throughput.
