Certain records will softlock the tool and result in a memory leak

[eur0pa]

To reproduce: dnstrace A baby.asda.com. Watch CPU load and memory usage.

Same for UI domains like 1und1.de, web.de, gmx.de. For gmx.com there's some output:

gmx_com.txt

I had to stop dnstrace from clogging my system with ulimit, otherwise the CPU is fully used and memory usage grows by on or more G every second...

This is a really nice tool I only discovered today, but the lack of response for almost a year is not very promising...
