Yes, such a bootstrap issue is hardly limited to IcedTea.
The same occurs with gcc for example, and other Free Java VMs.

You don't need stage 3 (there is no 'gcj dependency'), and stage 4 is completely optional.
Other Free VMs can be used, but they also have bootstrap issues.

In the long run, we probably need a binary option for lower spec. machines,
as I've already said.

Well this is probably a flaw in portage then, but the solution is only
a two-step emerge process:

emerge gcj-jdk
emerge icedtea6

I don't think that's inherently difficult.

I don't see any problem with 1.  Why is gcj not enabled in the bootstrap
gcc on the install CDs?

These are OpenJDK issues that need to be raised with Sun.
