/**
* \class AsyncModel asyncmodel.h Soprano/Server/AsyncModel
*
* \brief Filter model that allows to perform operations
* asyncroneously.
*
* AsyncModel has two modes: AsyncModel::SingleThreaded and AsyncModel::MultiThreaded.
* The main purpose of the AsyncModel::SingleThreaded mode is to protect a
* Model against deadlocks in a single threaded situation.
*
* AsyncModel::MultiThreaded mode provides real asyncroneous execution of
* Model commands.
*
* Usage:
* \code
* AsyncResult* result = model->listStatementsAsync( s );
* connect( result, SIGNAL(resultReady(AsyncResult*)),
* this, SLOT(slotResultReady(AsyncResult*)) );
* \endcode
