[gnome-db] Memory usage

Hi,

I try to use gda to connect to a mysql database. I used SimpleExample found in 
samples directory and changed dsn to match my needs.
This is only a connect/disconnect loop.
Here is the code:


#include <glib-object.h>
#include <glib/gprintf.h>

#include <libgda/libgda.h>
#include <sql-parser/gda-sql-parser.h>

#include <unistd.h>

GdaConnection *open_connection( void );

int main( int argc, char *argv[] ) {
     int i = 0;
     gda_init( );
     GdaConnection *cnc;

     for(i = 0; i<atoi(argv[1]); i++) {
         cnc = open_connection( );
         gda_connection_close( cnc );

         g_object_unref( cnc );
     }
     return 0;
}

/*
  * Open a connection to the example.db file
  */
GdaConnection *open_connection( ) {
     GdaConnection *cnc;
     GError *error = NULL;
     GdaSqlParser *parser;

     /* open connection */
     cnc = gda_connection_open_from_string( "MySQL", "DB_NAME=viewbox", 
"USERNAME=user;PASSWORD=pass",GDA_CONNECTION_OPTIONS_READ_ONLY,
                                           &error );

     if( !cnc ) {
         g_print( "Could not open connection database: %s\n",
                  error && error->message ? error->message : "No detail" );
         exit( 1 );
     }

     /* create an SQL parser */
     parser = gda_connection_create_parser( cnc );
     if( !parser ) /* @cnc doe snot provide its own parser => use default one */
         parser = gda_sql_parser_new( );
     /* attach the parser object to the connection */
     g_object_set_data_full( G_OBJECT( cnc ), "parser", parser, g_object_unref );

     return cnc;
}


There is no problem with sqlite but memory usage with mysql provider always 
increase (thanks to valgrind).
Is there any problem wth this piece of code ?
