Sorry, if my script find a file with the word "FLAG" in the name, I am going to move that file to a new location so that it does not get picked up by another deamon process until a later time.

If the initial script that I posted could work I could test for the existance for the word "FLAG" or at least test the return code $? i think.

BUGS
The network synchronization between client and server instances is weak, and does not prevent incompatible options from being used on the
two instances. The method used for retrieving work completions is not strictly correct, and race conditions may cause failures on some
systems.
