I suggested that to Fujii at pgcon, and it seems to work for him. But I
think this sucks since you loose support for a restart upon a FATAL or
similar error. And you cannot mark that as something non-fatal in the
log. To this day I laugh about the following oddity in the xorg log:

[    30.087] (II) RADEON(0): RandR 1.2 enabled, ignore the following RandR disabled message.
[    30.088] (--) RandR disabled

I really don't want to go there.

You actually can only return a 1 since everything else will tear down
the whole cluster...

We actually were discussing this recently:

I think a separate return code for "exited gracefully, don't restart"
would be a good idea.
