I think that the most recent change to Module.make will have fixed a
lot of the problems.
OTOH, I've just fixed some problems with NVIZ' Makefiles which
could have caused problems on parallel builds, and it's just luck that
you avoided those.
There may still be problems lurking. When it comes to parallel make,
testing is a fairly hit-and-miss concept, as most bugs depend upon
exactly when particular commands get executed, and it's practically
impossible to generate specific test cases.
 Or maybe made them worse. The reason I left NVIZ alone until now
was that the Makefiles were a mess. Although I fixed some obvious
problems, I may have introduced some new ones while cleaning up.
