Sadly, --nosync didn't seem to have any effect. There is a strangeness I 
've noticed in the log about halfway through the transfer:

...
bytes= 10 540 294 128 re-xmits=2147464 ( 29.6%) slice=0112  73 709 551 
615 -  59
bytes= 10 540 457 200 re-xmits=2147484 (-29.-6%) slice=0112  73 709 551 
615 -  59
...
bytes= 19 628 001 280 re-xmits=3351819 ( -6.-9%) slice=0112  73 709 551

Transfer complete.
