I was in the process of doing a large zfs send | zfs receive when I decided
that I wanted to terminate the the zfs send process. I killed it, but the zfs
receive doesn't want to die... In the meantime my zfs list command just hangs.
Here is the tail end of the truss output from a "truss zfs list":

Let me know if something else is needed to figure out what is going on.
The system is an x4600 running Solaris 10, with a fairly recent patch set.
