jack: "unlock memory" and "soft mode"

[Atte André Jensen <atte.jensen@xxxxxxxxx>]

Hi

I'm wondering *exactly* "unlock memory" and "soft mode" (as they appear 
in qjackctl) do? Moreover:

1) Are they advised to be selected or not?

2) Under what circumstances would a check in either be beneficial and 
when not?
