Hi Shane,

At some point, new sysctl types were added to the kernel, including
CTLTYPE_U32.  As part of the conversion to the counter(9) API, it
seems the v_wire_count (and other vm.stats sysctls) changed to U32
type.  py-sysctl lacks support for CTLTYPE_U32 and defaults to giving
you a bytearray for unrecognized types.

Best,
Conrad
