I suggest:

Create a class that hooks into transaction commit; look at ZPatterns
for an example of how to do this. Instances of this class will be
stored as a _v_deferred_deleter attribute of his link object.

manage_beforeDelete:
    create the _v_deferred_deleter attribnute if self doesnt have one
    self._v_deferred_deleter.deleted =3D 1

manage_afterAdd:
    if self has a _v_deferred_deleter attribute:
        self._v_deferred_deleter.deleted =3D 0

at transaction commit:
    if self._v_deferred_deleter.deleted:
        really delete the file
    remove self._v_deferred_deleter
   =20
