not writing anything to crawldb

[Fred Zimmerman]

I had to delete the contents of the  crawldb folder to recover from a failed
fetch (was this the best response? i doubt it).  now I have a fetch running,
successfully, but i don't see any evidence that is writing anything to
crawldb.  Is it going to write all the crawldb stuff at the end, or should I
go ahead and kill the crawl now?
