(OP)
I have noticed that on commercial aircraft all the windows have what appears to be a tiny hole in, presumably, the inner skin at the bottom of the window. What is this for?

The typical cabin window, behind that interior decorative pane, is made up of two plies. Some cabin windows have that tiny vent hole, for venting. Some windows do not have that vent hole.
As for loading, I have been involved in programs where both plies are considered structural. During cert testing in one program, with the outer ply failed, the inner layer withstood up to 40psi delta P.
