That may well be, and that part needs coder's attention.

But hardware DOES matter. Code fixes can't entirely solve that.

ZFS is just too demanding of resources for that rig [1] to usefully support in 
512MB of RAM, and 'dumb' controllers do not help.

NB: He does have decent power. External housing for the SATA array.

[1] Per his dmesg and a google of the various kit reported. Decent PCI slots 
aside, no longer a match for a current Mac Mini or a Dell laptop w/r RAM, CPU, 
or FSB speed.
