Don't want to send you on a wild goose chase, but I'd be interested to see the results of that and maybe the results of the same with an iSCSI backed blocked device vs nbd. I just thought there were some subtle differences between NBD and other "SAN" over network protocols. No idea how they'd play into the scenario you're describing however.
