[lxc-devel] [PATCH RFC] don't block signals until after we build signalfd

[Serge Hallyn]

Quoting Serge Hallyn (serge.hallyn at ubuntu.com):
> When we start a container, we first block most signals including
> sigchld, then create a signalfd fd for those signals.  This leaves
> a tiny tiny window during which signals may be lost.
> 
> So swap those.
> 
> In theory, AFAICS this *should* fix any race with container init
> exiting before we get to lxc_mainloop().  (In practice, a race
> remains - though it remains to be seen if this is a kernel or lxc
> bug)

Ok, sorry.  This cannot possibly be a problem.

Please ignore this patch.
