Data loss when Membership create calls a POST hook that fails (certain circumstances)

I have been able to replicate this in a test (have also hit it 'in the wild') - the test kind of explains the scenario - I have set against 4.4.6 due to catastrophic effects when it occurs - but will have to investigate the fix to determine if there is a simple or complex fix

// this call is our control - at time of writing this test passed & the one with the bad hook failed
$membership = CRM_Member_BAO_Membership::create($params, $ids);
$this->callAPISuccessGetSingle('membership', array('id' => $membership->id));
$this->callAPISuccess('membership', 'delete', array('id' => $membership->id));

$this->hookClass = CRM_Utils_Hook::singleton();
$this->hookClass->setHook('civicrm_post', array($this, 'badPostFunction'));

//if there is a rollback this second call will not create a membership
$membership = CRM_Member_BAO_Membership::create($params, $ids);
$this->callAPISuccessGetSingle('membership', array('id' => $membership->id));
