The new IO is after that one?


| About the question on how it refreshes: No, it does not use dnotify,
| inotify, FEM, FAM o any other file event handling mechanisms. That is
| still a nice-to-have that can wait for the moment.  Currently, it keeps
| the file cached for a period of time, after which it refreshes the
| cached data from the disk.

I have some experience lately with that :) I'll put that on my nice to
have todo list.
