while ((datastore = AST_LIST_REMOVE_HEAD(&chan->datastores, entry))) {
/* Free the data store */
ast_datastore_free(datastore);
}
I'll wait for more feedback before I post a new diff.</pre>

I'm going to go ahead and commit it, but I'd like to discuss this with the two of you tomorrow.</pre>

This was necessary because applications like chanspy could prevent channels from closing under certain conditions, causing the threads to become stuck and never complete.</pre>
