In order to reliably test the multihost protection we need two (or more) systems attempting to import the pool at the same time. Historically, we've used ztest running in userspace to simulate an active pool and attempted to import the pool with the kernel modules. This works but ztest is a bit unwieldy for this and if it crashes for unrelated reasons it can result in false positives. All we really need is the pool imported in userspace so the MMP thread is active and writing out uberblocks. We can extend zhack which already knows how to import the pool read/write and add an option to leave the pool open and idle.
