Description of problem:
Booting from the installation CD.  The entire installation process goes smoothly
until after packages have been selected for installation.  

Anaconda recognizes the hardware (I'm using an old Dell Optiplex GX111. 
Anaconda sees an Intel810 video card and a Dell M770 monitor).

The installation process is simple:
1. Select a generic 3-button mouse.
2. Choose to install a "personal desktop" (I also tried Workstation)
3. Choose to autopartition (I also tried manual partitioning)
4. Choose to "remove all partitions"
5. Select GRUB as the bootstrapper
6. Select DHCP to obtain IP address
7. Enable SSH (and DHCP)
8. Choose English as language
9. Select EST as the timezone
10. Set the su password and create one user account
11. Accept the default packages for installation

Anaconda now warns that the next step is not undoable.  I select OK.  The screen
changes to show two empty "progress bars", but within a few seconds, a dialog
box pops up with an error message:

Traceback (most recent call last):
 File "/usr/lib/anaconda/gui.py", line 786, in handleRenderCallback

  searchPath=1)

  childpid = os.fork()
OSError: [Errno12] Cannot allocate memory


I have used disk images from different mirror locations, and used 3 different CD
burners to create the installation CDs.  All fail in the same way.

I would certainly appreciate any feedback!  I've wasted far too many hours
trying to get this to work so that I can teach my students how to do the same
thing for a graduate course I'm teaching
