Problem found!

When you use the bash so much, you forget what you didn't have with the Bourne shell. Anyway, the problem is that you can't run mdsstart from the Bourne shell and logout, because it doesn't have the ability to disown the process.

This at first didn't make sense, but if you source the same CheckPoint script listed above with .sh on the end, and run it from a bash shell everything is fine.
