I am using GLFW 3. Window messages are handled in a different thread.  
As I understand, I must open-\>close-\>open a window to switch between fullscreen and windowed modes.

I am trying to make a fast fullscreen toggle(without losing OpenGL context).

Is it possible to achieve this with GLFW 3?

Not currently, but it will be added in the 3.x line.
