Bug#77761: apt: after dselect install w/ apt method, apt cache is rarely autocleaned

Package: apt
Version: 0.3.19
Severity: normal

Hi,

I began to notice that rarely does apt remove upgraded .deb from
its cache after a dselect install.  Here is a typescript that
shows this problem,

    114 jsroot ~ # dselect
    <update>

    }

    118 jsroot ~ #

what is weird is that sometimes upgraded packages _are_ deleted,
but this is happening more rarely as I do updates over time.

Thanks,
