Wouldn't it be more logical to prevent this from happening by not
using a refcount of zero? For example, NODELETE could just perform an
extra increment on the refcnt so that it never reaches 0. In essence,
the NODELETE flag is a permanent reference to the DSO.
I was thinking the same, without having looked yet. This does not sound
like the correct fix.
