Problem with background dumpcap in Windows

Running on recent builds on Windows, I've had a problem with dumpcap being
started and exiting repeatedly in the background. This seems to happening
when it's being restarted to update the interface statistics, such as
happens after a capture file is closed. The interface statistics update
just fine before opening a capture file.

My assumption is that this has something to do with my environment,
although I've blown away my build directory and rebuilt several times. I've
also rebased regularly against master. However, I don't know enough Windows
debugging to figure out what's going wrong.

I was able to see it happening with Procmon from Sysinternals. Should I
install Sysmon from Sysinternals to capture more information? How would I
get dumpcap to run under the debugger.
