Hi all,
with the big chunk of the Epetra_FE*Matrix allocations gone, I other
leak-like effects surface. Here's one with potentially larger impact,
Teuchos::reduceAll (which is called by virtually all dot-products).

Again, over time, the methods builds up more and more memory. It's
less clear to me how this happens though as reduceAll() itself is
const. It appears to be the create_contiguous call, and hence the
numBytes argument to reduceAll. From then on it's digging where those
calls are made.
