Subject: [PATCH 2/2] POSIX: Do not hang ScummVM when opening a browser
If the call used to open the browser does not return until the
browser is closed, this would previously cause ScummVM to hang.
Since we are using waitpid now, we can avoid hanging by telling
waitpid to not block on a child which has not exited.
