Details:

I detected memory leak about 0.6 MB/sec in my program. Valgrind showed that it
is MirrorNets in Pin constructors.

As I see MirrorNet cannot to delete itself :) I even tried to add next lines
to Net.RegisterNet

        // not good solution, but otherwise we get memory leak
        if(dynamic_cast<MirrorNet*>(connectedTo)){
          delete connectedTo;
          connectedTo = 0;
        }

But this causes other problems when pin is assigned to another pin. Pointer is
copied and MirrorNet is freed more than once.

There should be some solution. By the way, Pin.connectedTo is public which may
cause more problems.
