Changes (by lutra):

 * cc: pcav (added)
  * platform:  Debian => All
  * summary:  QGIS freezes while opening big shapefiles => QGIS take ages
              to open big shapefiles

Comment:

 The link to that shapefile is no more available, use this instead

 http://www.iucnredlist.org/spatial-data/MAMMALS_TERRESTRIAL.zip

 Actually the behaviour changed as QGis seems not to freeze anymore, it
 just take ages to open the shapefile and take even more to do any kind of
 basic (pan, zoom, etc.) operation. Using render caching do not seems to
 have any positive effect.

 Also configuring QGis to draw "x" features before updating the display
 (options -> rendering & svg) does not work for me.

 Tested on both linux and windows xp with QGis trunk.
