System V -- BATCH command

[M. D. Parker]

The MAN page for BATCH(1) and AT(1) lists information about both commands
together.  The man page indicates that invoking the BATCH command will 
wait to start a job "until system load permits".  

Exactly what does this mean?  

The BATCH(1) command is implemented via a shell script calling AT(1) with a
special option.  So it looks like things are run via CRON anyway.

If the statement means that a specified value of the system load figures
are checked, what are the defaults?  can you change the defaults easily?

Thanks...
