I'm also seeing this crash. zpool is one big SATA disk. Compression is 
turned off. This is amd64 with 1GB RAM. Everything except for / is on zfs.

This is very easy to reproduce at least on my system. So if you want me 
to run any commands from the debugger, please let me know.

Oh and BTW thanks for all your recent work on ZFS :-)
