I ran the script over iSER to backing stores of 8G lustre files and to
a 7G ramdisk and didn't see any problems.

for most of the tests the initiator nodes were run with 8G ram and then
again with 512M ram to try and flush more traffic down the wire.
I tried both osc.edu and mainstream tgtd's. no problems.
