[ale] perl nice'ness

[List]

I had to deal with something like this a number of years ago, where 
hundreds of scripts might have to be modified.  Rather than do that, we 
wrote a cron job to scan the process pool every so often and renice 
anything that popped up.  We also used the wrapper idea mentioned 
previously as well.

I guess it all depends on what you are doing, how the scripts are 
getting invoked, and whether you want to do it in the script code or 
externally.  There are certainly a lot of techniques available depending 
on the specific problem you have.
