Thats 'how' not 'when'. One of the dpkg manuals describes how the dselect
methods work and it boils down to using the *-avail functions in the
update script. Dats it.

Locking isn't the issue. If dselect is not using apt as the access method
then apt has no right to blow away the available file. The available file
is first and formost for use by dselect [in truth, any libdpkg based UI]
to communicate with the access method.
