Again, it depends on what sorts of commands are used in the BAT or CMD file.
  If they are commands that are internal, as in they are built into CMD.EXE,
then then that instance of CMD.EXE will utilize some CPU time as it executes
those internal commands. A small amount of CPU time will be utilized, too,
for the actual parsing of the BAT or CMD file itself. However, if there are
any external commands being executed as a result of processing the BAT or
CMD file, then those external commands will run in separate prcoesses and
will not result in CMD.EXE utilizing any significant amount of CPU time.

I don't understand what sort of work around you are asking for. This is
simply how CMD.EXE functions [and COMMAND.COM, for that matter]. While an
external console mode program is executing, CMD.EXE will appear idle as it
is in a wait state. The subprocess that it created to execute the external
command will then be busy or idle on its own depending on what it is doing
and how the user is interacting with it.
