Modified:
   short/3D/PyLith/trunk/TODO
Log:
Added known deficiency into TODO (can't mix fault and Dirichlet BC while using block Jacobian preconditioner- gives zero pivot).

+KNOWN DEFICIENCIES
+======================================================================
+
+  Can't use block Jacobi preconditioner when Dirichlet BC overlap with
+  fault BC's, because we end up with a DOF associated with a Lagrange
+  multiplier that is "free". Not sure if this is okay, when the fault
+  is at an angle to the boundary.
