The "capture child process" is now dumpcap; the only reason why the capture child process would try to pop up a window would be if, on an exec failure, it tried reporting that by popping up a window rather than just sending stuff on the pipe to the parent, and it doesn't do that.

So, yes, the comment is obsolete, given that...

...we're now doing exactly that, complete with the "even when we're *not* doing an "Update list of packets in real time" capture" part.
