[ROOT] Memory leak when printing canvas

Hi,

I would really appreciate if somebody could tell
me what I am doing wrong.

I need to generate a lot of plots at short intervals.
So I do a graph in a canvas and use the Print() method
to print a postscript file . But I noticed  that the
Print() method causes an increasing amount of memory to be
used. How can I prevent this and free the memory? 
Below is a sample code where
this can be observed (do top from a shell and watch...)

Any help would be appreciated. I use root 3.00 /egcs 2.91.66

Thanks,
		Tome

void testMemory()
{
Float_t X[100];
Float_t Y[100];

 TCanvas *c1;
 c1 = new TCanvas("c1","canvas");

 for (Int_t i=0; i< 100;i++) {
     X[i] = i;
     Y[i] = i;
 }
 TGraph* grh = new TGraph(100,X,Y);
 grh->Draw("AL");    

 while (1) {
     cout << " do plot " << endl;
     c1->Update();
	// this causes memory to be used and NOT freed
     c1->Print("xxx.eps");
 }
}
