Memory leak in pyroot

Looks like it is not a Python thing, if we run an equivalent C++ macro:

{

  TFile rtinput("tribic2017.root");
  auto meas_tree = (TTree*)rtinput.Get("measurements");

  auto nentries = meas_tree->GetEntries();
  for(Long64_t i = 0; i < nentries; ++i) {
    meas_tree->GetEntry(i);
  }

}

the same leak appears.

@pcanal any thoughts on this?
