-/** interrupt.c 
- *  
- * Fuse interrupts are handled using fuse_req_interrupt_func. Calling this registers a callback function with the req,
- * which may or may not be called either by fuse_req_interrupt_func, or later on via evfuse's event handler. It is
- * assumed that this will never be called after a call to fuse_reply_*.
- *
- * Hence, to handle an interrupt, we must first ensure that fuse_reply_* will not be called afterwards (it'll return
- * an error), and then we must call fuse_reply_err(req, EINTR).
- *
- * In the simplest case, we can simply submit a query, and then abort it once the req is interrupted (now or later).
- * In the more complicated case, we can check if the request was interrupted, if not, do the query and handle
- * interrupts.
