An excellent example of what Rob is alluding to is
73P/Schwassmann-Wachmann 3, which split into four fragments in 1995.
Recently, Hartwig Luthen, Rainer Arlt and Michael Jager wrote a fascinating
paper for WGN (February-April 2001 29:1) in which they note that the dust
trail produced by the 1995 fragmentation may encounter the Earth in 2022.
Since the miss distance rD-rE is equal to 0.0004 AU, they express hope
that some activity will be noted, since there is a chance that " . . . the
trail is more populated due to the massive expulsion of dust observed in
1995."
