Yeah, that's typical. I think the only real solution is to alter the mesh itself.
UVmapper does a pretty good job of aligning normals. Copy the original OBJ
file so you don't lose it; take the OBJ file into UVmapper; select each of
the groups (or materials) that has holes, and hit Tools:Facets:Align.
If it's working right, you'll see a notice that says a small number like "3 facets inverted".
If that wasn't the problem, UVmapper will say "zero facets inverted".
