This is not surprising. ZFS can also have problems when put on top of 
some other system. These filesystems are made to be on the bare drives 
and generally to provide their own raid/lvm interface (though btrfs 
doesn't yet have a full raid implementation like zraid on ZFS).

I have been running ZFS on an SSD with /, and an HD with subvolumes for 
/var, /tmp, /etc and /usr without any problems. Quite fond of subvolumes 
too, it seems like a good way to break up and even limit a directory's 
space without having to create a ton of separate partitions. The issues 
seem to be related to a few usage scenarios, and will of course continue 
to get better with every kernel release.
