See this line:

         provider.select(allAttrs, QgsRect(), False)


you should use QgsRect ( x0, y0, x1, y1) to limit the search range.
Otherwise, it will return all features.

an example, taken from your source code:

         provider.select(allAttrs, QgsRect(p.x(0)-0.5, p.y(0)-0.5,
p.x(0)+0.5, p.y(0)+0.5), False)


try it!

p.s. Please don't answer *directly* to me, but to the group!
