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).
