It must not block accesses, this is my concern. No OOM now, but double the number of files and IMHO glusterfs will grow up to 1.5 GB. Thank you for doing the test. Now we should check, whether fuse_forget() is called at all during the test. I would not assume blindly that it is. yes -> glusterfs problem no -> fuse bug?
