  | I was expecting it to work (i.e interrupt read again and call foo)

Isn't that what it did?

But I see what you mean now, during the read that's called from the
trap execution call of foo, SIGINT is blocked - that most probably should
not happen, and it looks as if when the trap handler exits, the
original read is resumed, that certainly shouldn't happen.

Still, I don't believe that the way the function is written is a way
that you can expect will work necessarily.
