With the lint mode set to background every time I save a file I get the spinning beach ball for a few seconds and the user interface is frozen. Presumably the plugin is running cflint and waiting for that to return which ties up the user interface. I base this assumption on when I run CFLint from the command line it takes about the same amount of time to process the file as the interface is frozen when I save.
