[gdal-dev] Update on RFC 45 - GDAL datasets and raster bands as virtual memory mappings

[Even Rouault]

Hi,

I've investigated memory file mapping mechanisms and added that to the RFC.

You'll find the diffs w.r.t the version I submitted 3 few weeks ago :
* http://trac.osgeo.org/gdal/wiki/rfc45_virtualmem?action=diff&version=6
* http://trac.osgeo.org/gdal/wiki/rfc45_virtualmem?action=diff&version=7
* http://trac.osgeo.org/gdal/wiki/rfc45_virtualmem?action=diff&version=8

The implementation patch has also been updated :
http://trac.osgeo.org/gdal/attachment/wiki/rfc45_virtualmem/virtualmem.patch

If this does not raise further discussions (which are welcome), I'll call for 
a vote soon.

Best regards,

Even
