Howdy All,

    I've recently showed some of our uVax II users how to do run commands
with both input and output being to and from files instead of interactive
IO.  They've taken to doing much of their Lindo (a linear programming 
package) work this way.  Once they do a :

        "Run /input=foo.in/out=foo.out foo.exe"

     the job spawns a sub-process and goes on its merry way.  I've
noticed that these jobs are hitting huge page-fault rates ( usually
over 300 on the "monitor system" display ).  Have I created monsters ???
Is it bad to run large programs in this mode ???  Am I unnecessarily
killing the system ???

      Any answers to these questions would be appreciated.  Thanks !
