This is not a regression at least (I have just tested on 1.2.1). There
is still a lot of work we can do to make this better - but this will
have to wait for 1.4 I believe, because those are really hard to get
right (they depend on both C runtimes and python versions).
I will look at the mac thing, I wonder why it only appear on this OS,
though,
cheers,
David
