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).
