Try starting the process detached:
spawnvp(_P_DETACH, argv[0], argv);
Without a doubt that will work, since the call to
fhandler_console::need_invisible
is conditional on the mode not being _P_DETACH.
The problem is that sometimes you don't want this detach behavior.
Secondly, this child_info_spawn::worker is used underneath various
functions: exec*, spawn*, popen, system. Not all these can pass through
_P_DETACH at all.
(I'm only using spawnvp for the sake of producing a minimal test case).
