You can, and should use a regular [Command](http://rdoc.info/github/puppetlabs/puppet-acceptance/master/PuppetAcceptance/Command) instance here, instead of the HostCommand. HostCommand has a very particular use case (it was an over optimization for a paralleling test execution) but I loathe it's [implementation](https://github.com/puppetlabs/puppet-acceptance/blob/master/lib/puppet_acceptance/command.rb#L237-L241) and I don't believe this is it.

I'm sorry, grepping through the code I see that this usage of HostCommand was in another PR that you submitted and I didn't notice. I should have caught this then.
