ok, then would it be a workaround to add a python qgis-api method for
this? Or will we have the same problem then? ( the
QgsProject::write()-method emits a 'writeProject'-event which will be
received by the python part again. isn't it? ).

Otherwise, should we conclude that it is not possible to save a project
via python then (and in case of mapserver plugin I would let user NOT
use plugin without a saved project in the beginning anyway...)?
