I can''t reproduce this.

I need access to the machine when the hang happens.

I just reproduced it. You can reproduce on data16.sfbay according to my steps. 

I''ll leave the test machine hang at the end of today for your
investigation.

As Grace and I discussed on the phone, this test case isn''t valid for
the key
change since the two files are different.. but the fact that zpool key -u hangs
is the important issue here..  I will investigate if I can reproduces this..

I believe this was caused by bug 2065.  Because the dataset was not being
unmounted, it caused a hang.  My guess is the copy operation  in the example
was being done when the key was unloaded..

*** This bug has been marked as a duplicate of bug 2065 ***
