I'm against having this logic reside here, it can be in a helper class..VDS
command should just execute the vds verb as we do in all the rest of the
commands. It can be extracted to an helper class which will fit better IMO.

possible race with getIsoPrefix(), are you fine with that?
we already have the eventqueue interface/infra for serializing events on a
pool, perhaps you could use it as well,.
