I guess it's from Filesys::Notify::Simple. Which OS are you using?
It should be able to use inotify / kqueue depending on whether
you're on Linux or FreeBSD (I haven't tested other BSDs). It
uses Linux::Inotify2 on Linux which AFAIK all deb-based distros
will pull in, and Filesys::Notify::KQueue on KQueue-supported
systems.
