Thanks for testing the new gmultipath patches! I just want to say that 
you should test 4BSD/ULE very carefully before making any conclusions 
because ULE fails in very, very specific edge cases which are not very 
common. I've done this 4BSD/ULE test just for laughs on an network 
IO-intensive workload on a 24-core machine and the performance with 4BSD 
was laughably slow (which is expected as it is of a very old design).
