If you put tmod in both libraries, you'll have two copies of it, and two  
copies of the data. Can't you join both libraries onto a single one? Or  
make one load the other? Or avoid global variables, and pass the required  
data to the subroutines? Either way, this is a design problem that you'll  
have to solve on the Fortran side, not in Python.
