On a Solaris 11 (SR3) system I have a zfs destroy process what appears
to be doing nothing and can't be killed. It has used 5 seconds of CPU
in a day and a half, but truss -p won't attach. No data appears to have
been removed. The dataset (but not the pool) is busy.
I thought this was an old problem that was fixed long ago in Solaris 10
(I had several temporary patches over the years), but it appears to be
alive and well.
