stopping long running actions

I have been trying to find a way to stop a long running action. The method I have been trying is using an around filter with the Terminator gem (http://www.lindsaar.net/2008/9/11/terminator-timeout- without-mercy) however the Terminator gem doesn't seem to play well with mongrel. testing it in script/console gives the expected results, but when I use it with script/server Terminator halts the mongrel entirely. I dug through mongrel Signal.trap calls and tried a few different signals, but I never got anything to work. I tried both the standard Timeout Module and SystemTimer with even less luck. So the question is, has anyone else been able to get a similar setup working? How would you stop long running requests? Thanks, Doug
