+\subsection{Common Options}

+Following options used by many modules, so they described in separate section.

+\subsubsection{Option \texttt{iqdisc}}
+
+Many modules define handlers for processing IQ queries of different namespaces
+to this server or to user (e.\,g. to \texttt{myjabber.org} or to
+\texttt{user@myjabber.org}).  This option defines processing discipline of this
+queries.  Possible values are:
+\begin{description}
+\item[\texttt{no\_queue}] All queries of namespace with this processing
+  discipline processed immediately.  This also means that no other packets can
+  be processed until finished this.  Hence this discipline is not recommended
+  if processing of query can take relative many time.
+\item[\texttt{one\_queue}] In this case created separate queue for processing
+  IQ queries of namespace with this discipline, and processing of this queue
+  done in parallel with processing of other packets. This discipline is most
+  recommended.
+\item[\texttt{parallel}] In this case for all packets of namespace with this
+  discipline spawned separate Erlang process, so all this packets processed in
+  parallel.  Although spawning of Erlang process have relative low cost, this
+  can broke server normal work, because Erlang have limit of 32000 processes.
+\end{description}

+\begin{verbatim}
+{modules, [
+           ...
+           {mod_time,      [{iqdisc, no_queue}]},
