Is there any way to set the MaxVirtualSize for all TTrees contained in
a TChain?  Would I just use TChain::GetNtrees() and iterate over the
TTrees (using TChain::LoadTree()), calling the
TTree::SetMaxVirtualSize() function on each?  Or am I missing some
easier way to do it?  (Calling chain.SetMaxVirtualSize() didn't seem
to work.)
Thanks,
Reid
