      From Robert:
            There is a real issue with the time it takes megatest to process runconfigs.
      
            Every #{shell ...} command is processed in every target from every included
      file even if the target is not the one being run, or a simple -list-targets
      is given on the command line.
      
      To make matters worse, when running a regression, not only does the main
      megatest "mtest" call processes runconfigs, so does any server started by
      the regression run.
      
      And if it takes a LONG time to process the runconfigs, the regression run
      will spend a lot of time waiting for the server to start.
            Every single call to megatest, whether its to start the regression, or start
            a server, or whatever, is subject to the time it takes to process the
            runconfig files.
      
            The parsing of runconfigs should happen 1 time per session, and the
            evaluation of value should only happen 1 time and when its needed/used
            (there should not be a global evaluation of all parameters across all
            targets unless there is some kind of dump operation occurring).
      
      While I appreciate that there was some original reason/intent for re-parsing
      the runconfigs the entire process is leading to a substantial performance
      issues in regression runs. Even if there is a need to re-evaluate a
      variable value, there should be a means of indicating so, like:
      
            VAR #{eval ...}
      
      Something needs to be done to improve performance of reading the runconfigs.
