Indeed.

But here's something else to ponder...

I've been using ZFS since it was internal beta at Sun, at first on i386 
and later on amd64.
I've never run into this kind of panic on Solaris.  System can get very 
slow, yes, with
ZFS hogging lots of memory, but it never panic'd because of it.

We need to come up with a strategy here to solve this problem, be it 
fixing the kmem
virtual memory or fixing zfs.
