Restartable system call behaviour

Fair enough, that answers my question!

Have been puzzling over this a lot actually, as I definitely didnt get
it on 4.11. The conclusion I've come to is that the networking circumstances
have also changed over time, such that it's now more likely for me to get
a signal during a connect, hence it probably always did behave that way, just
that I never saw it. The change to 5 would be a co-incidence then.
