[Trilinos-Users] Updating values in a Tpetra CRS matrix

I currently use an Epetra crs matrix in a newton-like solve where I am
repeatedly changing matrix values (but not the structure) and
performing linear solves.
I'm interested in switching to Tpetra for it's multithreading (OpenMP)
support, but I see that the Tpetra documentation says that a CRS
matrix can't be changed after fillComplete() without making a
resumeFill() call and then another fillComplete() after changing
Given that fillComplete() is expensive, is it feasible for me to use
Tpetra in my use case?
