I've used PPerl for deamon like processes. This program turns ordinary perl scripts into long running daemons, making subsequent executions extremely fast. It forks several processes for each script, allowing many proceses to call the script at once. Does anyone know of something like this for ruby? Right now I am planing on using a wrapper around curl to call a REST WebService written in Sinatra running on JRuby. I'm hoping there is a simpler option.
