Unreleased space after deleting files

[STSISI-sigo]

Description

This issue follow the #37 When we have not enought space in the apache temp filesystem, the temporary files are now deleted in the 1.7.0 version but some space are unrealesed by the qgis_maps process.

Context

Qgis server is using with apache2 and fcgi. When we call the plugin for a large file, send with a SHP outputFormat for example, the plugin create a gml file, then he converts this one in shp and finally in a zip file. All theses files are deleted when no error and the final file is send, and when an error is occuring, the plugin stop, send a corrupt file and delete the temporary files but the space is not integrally unrealesed, qgis_maps process keep some space with the deleted files. We must restart apache to unrealsed the space.
