type SerialDriver added in v0.5.1

type SerialDriver struct {
	Driver
	sync.Locker
}

SerialDriver is a wrapper struct which is used to ensure that RPC calls to a driver only occur one at a time. Some providers, e.g. virtualbox, should not run driver operations at the same time as other driver instances of the same type. Otherwise, we scrape up against VirtualBox's own locking mechanisms.

It would be preferable to simply have a lock around, say, the VBoxManage command, but with our current one-server-process-per-machine model it is impossible to dictate this locking on the server side.
