Title:
  Blender(2.49b) uses up swap space, crashes system

Status in blender package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: blender

  First off:

  Ubuntu release: 10.04 LTS(Lucid Lynx)
  Blender package version: 2.49.2~dfsg-1ubuntu1
  Blender version 2.49(sub 2)

  OpenGL vendor: Tungsten Graphics, Inc
  OpenGL version: 2.1 Mesa 7.7.1
  OpenGL renderer string: Mesa DRI Mobile Intel® GM45 Express Chipset GEM 20091221 2009Q4 x86/MMX/SSE2

  What I expected to happen: Basically, nothing. I could just model as normal.
  What happened instead:

  Blender, after a while(around 5 minutes), starts to slow down and use up a large(95%) amount of swap space, while RAM usage stays below 30%. After 5 more minutes, Blender hangs the entire system(most likely due to lack of swap space), and I have to cold reboot to restart the system.
  The problem seems to become worse if I scale/rotate.

  How to reproduce:

  1. Open up Blender(fullscreen or windowed)
  2. Add a few primitives
  3. Scale or rotate them
  4. Render them a few times, and add a few lights. Rotate them
  5. Render again

  By step 3(most certainly by step 5), you should experience system
  slowdown, and by step 5, Blender should hang, along with the entire
  system.

  Opening the System Monitor should reveal around 95% of swap space
  usage, while RAM usage is still below 30%.
