(1) We add FUSE support directly to the API, linking with libfuse.
This is essentially the same as what was outlined in link [i] back in
December 2011.

The problem with (1) is that we are not confident that it's a
good
idea to use libfuse as a true library. It doesn't appear that anyone
else is using it this way.
I'll also add that libfuse makes it tricky to use multiple handles.
Specifically, FUSE callbacks get no context at all, eg: getattr's
parameters are:
static int getattr (const char *path, struct stat *statbuf);
If libfuse could be called from multiple threads, each with its own
handle, then how would you know which handle to use? (The answer
possibly involves using thread-local storage, but that's hairy if
either handle is multithreaded).
