My earlier guess as to which patch might cause it was probably wrong.

It looks like an fd handle which is connected to an unlinked file is
reused. this sucks, however, it's not the real flaw. the real flaw is
that where it fails to get cleaned up in the first place and thus "looks"
still in use so we continue using it.

apparent side effect: the "ih_ino" in the ihandle appears to be bogus.

this smells a lot like the infamous copy on write bug. it's probably
similar though not the same
