8.1-release + zfs v15 df(1) hangs

  Hi All,

i installed freebsd 8.1-release on my workstation (based on the 
8.1-release mfsbsd isos) and I'm now experiencing some strange effects.

A df(1) doesn't return and is not killable and while taking a look 
around in my process table, I could find several find's hanging around too.

I couldn't figure out where they're coming from, but since it seems 
there's a new one every night I suspect its coming from a periodic script.

Any ideas how to get rid of those processes?

And yes, I know that zfs V15 isn't in -STABLE for a reason...

(I csup'ed to RELENG_8_1 and applied the v15 patch from 
http://mfsbsd.vx.sk/ and did a make world)
