[Openstreetmap] qgis isn't so memory hungry

I believe this is a problem with the GPX import filter, not with qgis
in general.  I tried to convert the GPX files to shapefiles using the
gpx2shp program available from <URL:http://gpx2shp.sourceforge.jp/>,
and imported the resulting shapefile info qgis.

I imported track-2004-01.gpx (462639 points) and track-2004-11.gpx
(133806 points) this way, and the resulting qgis binary is 17 MiB.
The gpx2shp convert process was >500 MiB at its largest. :)

Thus suggest to me that the GPX import filter in qgis (and the gpx2shp
convert program) uses a lot of memory, and that qgis is not the memory
hungry one.
