They still are! I can only wonder why?! The information I just
posted was filtered out off multiple LWPs (three per process).
The most "realistic" of them has a pointer into db() function on
the top. The thing happend 25 times in ~15 hours.

I also must admit that I *do* have a custom db lookup function, so
theoretically it might currupt the cache one way or another (and no,
I cannot run the thing without that custom function). I modelled
it after hostname lookup function, it's quite simple: search only,
get a string, s=dupnstr(infostr,strlen(infostr)); return
Anything I could do wrong here?
