Well, the fix is here, simpler than I thought. You missed a line here:
 cachevar=_deb_packages_cache_uninstalled

Now "aptitude install a<Tab>" responds quickly(within a second) and
correctly. Thanks for your help, Bart! I have learn quite a bit shell
scripting along the way.
On the other hand, I think the performance can be further improved. A
delay of 1s is good enough for me but not good enough for some.
