But it's not ZFS+tmpfs specific, it can happen anywhere when memory
and swap is not sufficient.  Of course tmpfs and ZFS should play more
well together but it's pretty much a "you get what you paid for"
situation IMHO.

One thing I can not yet reproduce, but sounds like a serious issue is
that when system have sufficient RAM available, ZFS reports 0 in free
space...  If there is a test case for that then that's definitely
something we need to solve sooner.

Cheers,
