It does, in fact, have ktrace. What a neat program!

Here's the last bit of the trace for avarice:

And the last bit for avrdude. Interesting to note: avrdude manages to  
also output "Found JTAGICE mkII, serno: 00A0000033FA" before it  
hangs, but I don't see that in the trace output. I waited 10 seconds,  
then typed control-C.
