The new FUSE loop use a Windows event (LoopEvent) to signal loop exit.
Prior to this commit the Windows event was created outside the FUSE
loop and potentially before daemonization (on Cygwin). This means that
the event was created in a different process and
WaitForMultipleObjects was failing with ERROR_ACCESS_DENIED.
This commit ensures that the LoopEvent is created inside the FUSE loop
and therefore in the daemonized process.
