<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Yes it is now safe there was one case where it could sneak past the bit bellow is when a member is created and no device state assigned the member is removed.
there was the ability to change the state_interface in the RT backend where it will be reassigned if this fails the member is marked for execution now.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I'm guessing that if a new member can't get a device here that this is going to deref the member to zero and destroy it. So I'm assuming for the moment that the assumption is safe.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This is a rather large changeset but consists of the following
1)remove the taskprocessor it was used to process the state changes and this is perhaps not that efficient
2)remove check_state_unknown its not needed any more now that we can reserve a state interface
3)split state information into a new container (devices) the member holds a ref to it allowing shared state devices see above
4)realtime and paused are y/n so add a :1 to them and align bitfields in struct
5)ao2 search callbacks can handle non OBJ_POINTER flag to make ao2_find useful no need to pass obj
6)Reservation of devices to pervent duplicate calls

check state information is propogated and used in app_queue [3,6]
make sure queues are loaded correctly and changes in [5] have not broken things</pre>
