[issue2466] os.path.ismount doesn't work for mounts the user doesn't have permission to see

Pablo Sole added the comment:
I found another case where the result of ismount() is misleading. I'm using a FUSE-based filesystem controlled by a python supervisor daemon.
When the fuse daemon dies and you try to access the filesystem with os.stat() it returns:
OSError: [Errno 107] Transport endpoint is not connected: '/tmp/fuse-test'. Although, the filesystem is actually mounted and you can verify this:
# cat /proc/self/mountinfo | grep fuse
26 25 0:20 / /tmp/fuse-test rw,nosuid,nodev,relatime - fuse /dev/fuse rw,user_id=1000,group_id=1000,default_permissions,allow_other
If the idea of ismount() is to show what paths are mountpoints, in this case it should return True, even if it's non-accessible (the fuse daemon died in this case, it might also happen for a stale NFS mount *not checked* ).
