Major Description
Tailer would benefit from using Java 7's WatchService to detect file changes instead of polling at a set interval. Tailer could respond quicker to changes, and it would save the system from constant polling. This of course would mean that commons-io would require Java 7.
I don't know what the future release plans are for commons-io; if there's an upcoming version that will require Java 7, I'll happily make this change myself.
