I'm not sure if anyone has mentioned this yet in the thread, but another thing worth taking into account in considering the stability of ZFS is whether or not Sun considers it a production feature in Solaris. Last I heard, it was still considered an experimental feature there as well.

Last I heard, rsync didn't crash Solaris on ZFS :)

My admittedly second-hand understanding is that ZFS shows similarly gratuitous memory use on both Mac OS X and Solaris. One advantage Solaris has is that it runs primarily on expensive 64-bit servers with lots of memory. Part of the problem on FreeBSD is that people run ZFS on sytems with 32-bit CPUs and a lot less memory. It could be that ZFS should be enforcing higher minimum hardware requirements to mount (i.e., refusing to run on systems with 32-bit address spaces or <4gb of memory and inadequate tuning).
