Even if something is holding the file open, that wouldn't prevent unlink
from removing the directory entry for it; or even if we were talking
about a badly-designed filesystem that failed to follow standard Unix
semantics, that wouldn't explain why the directory entry is apparently
visible to some operations but not others.
Still, I agree with your point: Thom should reboot and see if the
misbehavior is still there, because that would be useful info for his
bug report.
