shared folder doesn't seem to update

[Till]

I ran into an issue where when I change a file on/in a shared folder, the change is not seen when I serve up the file through a webserver (e.g. nginx).

I originally reported this with ​vagrant, but they directed me here. I tried 4.0.8 of course already. This issue is present on at least two operating systems (Linux und MacOSX).

The guest in both cases was Linux (Ubuntu Karmic 9.10). I can provide my image if necessary --- it's a vagrant box.

Per ticket I previously opened (on github, vagrant), it seems to be an issue related to the syscalls of sendfile.

Let me know if I can provide more information or test.
