in thread Hunting for a memory leak

Looking in the POD for Tk::Image it says:

CAVEATS It's necessary to use the "delete" method to delete an image object and free memory associated with it. Just using a lexical variable for storing the image object and letting the variable to go out of scope or setting to undef is not sufficient.

That said, I tried adding 

    $ZC->centerTags($dwg);
    $img->delete;
    undef $img;

And it made no difference.

In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
