incron sounds promising. I could use the regular cron to push a signal (ie. 
touch a file) at the regular interval, whereupon incron launches the 
existing script, and the webscript can touch the signal file when I need 
the script run right away. Will incron not run the script again if it's 
already running? Will it queue the file event until the handler exits?
