Where this came out of was requests from various partners and ISVs
who noticed that their 32-bit apps didn't run right on ia64 with
the /emul/ia32-linux prefix. This is due to some of the fundamental
issues with that arrangement:

- 64-bit processes don't see into that tree because of their personality
(think: shell scripts)
- the results of readdir() on a directory in /emul/ia32-linux will not
necessarily match the files you can actually access with open()

The simplest way to solve this, while maintaining compatiblity with
ia32 packages, is to get them on the same filesystem. This is where
the proposal stemmed from, originally.

We can always just live with crappy ia32 (and by extension,
x86-64) support on ia64. :)
