[arch-general] i3wm (randomly?) freezes; SIGCONT seems to fix it

[Martin Kühne]

Just as an aside from a technical perspective: Keep SIG_IGN vs SIG_DFL
in mind. I guess signals are passed from the child process to the
parent? Then again, I don't know where setsid() comes into play,
whether i3 does it / does it correctly, and whether that has an effect
on the signal processing queue.

SIGCHEERS!
