These look like well known problems with ZFS (see http://wiki.freebsd.org/ZFSKnownProblems). A new version of the ZFS port is currently under development, if you want to try it, you need a 8-CURRENT machine and this patch: http://lists.freebsd.org/pipermail/freebsd-fs/2008-July/004887.html People have reported that the new patch resolves hangs such as yours.
