Description of problem:
On _really_ fast machines (XP 1800+) with 333MHZ bus, promise IDE controller,
and 56x CDROM causes race conditions in the installer to come through.
Mozilla package is still running pre-install scripts when the installer tries to
unmount the CD-ROM. This causes a crash due to "Device busy" being returned
(Some files are still open on the device).

Version-Release number of selected component (if applicable):
Default on installation CD of RedHat 7.3

How reproducible:
Sometimes

Steps to Reproduce:
1. Select packages (Specifically Mozilla libs and mozilla packages).
2. Start installation
3. Soon before the prompt for next CD (and after unmount of CDROM) the race
condition might (or might not on slow machines) occur.
	

Actual Results:  - Installer crashes completely (Debugging the Python code shows
it crashes on umount().
