This is a bug in procfs not deleting the dentry for the file.
It's been there for a long time now... (You can easy cause this
with binfmt_misc, too)
I suppose, this will not be fixed until the VFS has finally moved
to dentries and procfs has got a 'little' overhaul.
BTW I reported this bug twice some time ago...
