[meteorite-list] Cyclic meteorite streams?

[E.P. Grondine]

Hi all - 

This seems a good a time as any to being this topic up
once again, as the ISS is given a chance of somewhere
between 1 in 20 to 1 in 100 of being holed by ordinary
man made space junk. 

While many have taken a look at annual fall patterns,
I have often wondered if some meteorite falls are not
instead cyclic, in other words come from intercepting
recurring debris streams from asteroids? 

Along those lines, why are meteor showers (comet
debris stream intercepts) annual, and not cyclic on
another basis?
