It *should* just quickly fail, so that dumpcap can fall back on "I guess that's a pipe".
Actually I guess that WinPcap's pcap_open_live() somehow calls exit(127)... Not
that I expect WinPcap to call exit() at all, I have no clue why this behavior
now shows up and not earlier... All parameters provided to the pcap_open_live()
call make sense (to me)...
