glist doesn't free mem

["Aldrin Martoq A." <agm cec uchile cl>]

Hello, I was wonder why my test app consumes more and more memory... So I
make a little test and found that glist doesn't free !!!

-----1.c-------
#include <glib.h>

typedef struct
  {	guint ano;
	guint sem;
	gchar *dep;
	GList *cur;
	gchar *coment;
  } CatCatalog;

  
main(int argc, char **argv)
  {	int i,j;
	int imax = atoi(argv[1]);
	GList *l = NULL;
	
	g_print("enter empieza");
	getchar();
	
for (j=1; j<=2; j++)
  {	l = NULL;
	g_print("alocando %i elementos ...", imax*j);
	for (i=0; i<(imax*j); i++)
	  {	CatCatalog *c = (CatCatalog *) malloc(sizeof(CatCatalog));
		l = g_list_append(l, c);
	  }
	g_print(" ya");
	getchar();
	g_print("liberando %i elementos ...", imax*j);
	for (i=0; i<(imax*j); i++)
	  {	CatCatalog *c;
		c = (CatCatalog *) g_list_nth_data(l, i);
		free(c);
	  }
	g_print(" ya");
	g_list_free(l);
	getchar();	
  }
  }
----eof---

compile with "gcc 1.c -o 1 `glib-config --cflags --libs glib`". Then:
% ./1 10000
enter empieza				# top says 396K
alocando 10000 elementos ... ya		# top says 784K
liberando 10000 elementos ... ya	# top says 784K !!!!!
alocando 20000 elementos ... ya		# top says 1140K
liberando 20000 elementos ... ya	# top says 1140K !!!!!

I don't understand why if I free'd everything, its still there. If I use
an array instead of GList*, top says what I expect...

What am I doing wrong?
