To speedup the compile time, maybe we should try to use the mean()
operator in FFC for the stabilization terms, replacing w with wm
in these terms with

wm = mean(w)

Did you try putting the common stuff in a common .py file and import it?

An unrelated question: would Johan H mind changing the names of the
.form files to NSEMomentum2D.form etc (without the _) etc so the
naming is consistent throughout the code?
