Review Comment:
   I didn't want to hold references to the objects such as the `FileSystem`, 
I've modelled it to be in line with the `File#deleteOnExit` implementation of 
openjdk which was using `String` instead of `File` to keep those. But I don't 
foresee any real problem keeping references to `Path`, provided that we do use 
the `toAbsolutePath()`.
