 Layers built with the memory data provider should not be saved to the
 project file, as when the file is reloaded, the data for the layers is no
 longer available.  This means that reloading the project does not restore
 it to its saved state.

 I think that when Quantum saves a project then it should check for in
 memory layers, and provide the option of saving them to a persistent
 provider, or removing them from the project.

 Also it would good when an in memory layer is saved to a shapefile (or
 other persistent provider) from the legend right click menu if the layer
 was replaced with the saved layer.  This make it much easier to make in
 memory layers persistent in the project.  At the moment I think you need
 to save the layer, then load the saved version, and then remove the in
 memory layer.
