<p>Callback space behaviors describe how a space behaves. </p>
<p>In a non-threaded build all spaces exhibit a behavior == _BEHAVIOR_SINGLE. Setting a specific behavior in this case is ignored.</p>
<p>In a threaded build, _BEHAVIOR_SINGLE retains all the rules and behaviors of a non-threaded build while _BEHAVIOR_THREADED makes the space act as the global space.</p>
<p>Setting a space's behavior to _BEHAVIOR_SINGLE guarantees that the poll protection will always be there and all callbacks are serialized and only kicked out when polled for. In a threaded build, it is still necessary to poll for callbacks in a _BEHAVIOR_SINGLE space.

<p>Setting a space's behavior to _BEHAVIOR_SERIALIZED guarantees that the poll protection will always be there and all callbacks are serialized. In a threaded build, it is NOT necessary to poll for callbacks in a _BEHAVIOR_SERIALIZED space. Callbacks in this space will be delivered as soon as possible, but only one outstanding (and unblocked) callback will be allowed at any time.</p>
<p>Setting a space's behavior to _BEHAVIOR_THREADED allows the user to have the poll protection provided by spaces when built non-threaded, yet, be fully threaded when built threaded (where poll protection is not needed) </p>
