There are several interesting things: 1. less NFS traffic [as we potentially access less files] 2. faster loading time [in case the user tune it's execution environment] 3. (1) + (2) -> faster startup time [at least everything which do not depend on the network] 4. MX bug will go away if the pml is specified. 5. No useless BTL will be opened, which will solve few others issues. This commit was SVN r15402.
