Great idea!

I have implemented it partically, just fetching some fields we needed, and resuing feature object, directly reading geometry(WKB foramt) object from shapefile file, and resuing geometry object.

maybe, we can read a block from shapefile one time, and parse it to some geoemtry objects, and this memory block should be resuing.

these method will speed up reading geometry objects and attribute from DBF and shapefile.
