The reason\nis that while all other threads will exit, the mounting thread (or process)\nwill keep the device fd open, which will prevent an abort from happening.\n\nThis is a regression from the async mount case, where the mount was done\nfirst, and the FUSE_INIT processing afterwards, in which case there's no\nsuch recursive syscall keeping the fd open."
