/**
 *  @brief _Thread_queue_Extract_with_proxy
 *
 *  This routine extracts the_thread from the_thread_queue
 *  and ensures that if there is a proxy for this task on
 *  another node, it is also dealt with. A proxy is a data
 *  data that is on the thread queue on the remote node and
 *  acts as a proxy for the local thread. If the local thread
 *  was waiting on a remote operation, then the remote side
 *  of the operation must be cleaned up.
