        Sweeping bugs under the rug is not what I plan on doing; I’m marking 
these as expected failures, as opposed to having them continually panic a 
machine. Once a ZFS dev takes a look at the issue and resolves them, then the 
ZFS dev can remove the “bail” calls I’m adding to the testcases.
Cheers,

PS FWIW the panics are recent. As I stated in the first bug, it didn’t occur on 
10.0-RELEASE.
