Userland (UX) Runtime

[Michael J. Emswiler]

When comparing differences between your output and the output of my K7-GCC4 
binary, I notice the following differences:

1.  Your kernel is 2.6.13.2, while mine is the default 10.1 kernel of 
2.6.16.13-4

2.  After the "Loading Module..." messages and before "Bootstrapping...", mine 
shows :
Copying Module 0x039be000-0x039e0c99 [hello]

3.  Your running a Pentium-M (I'm running a K-7), so my TLBs and Caches are 
different.

4.  My init code/data freed is 7 pages.

5.  I don't get a SIGSEGV after MIKEE: Exiting Thread::initialize(), it 
appears to go into a tight loop that ignores CTRL+C.

Not sure what all that means but thought I'd point it out in case someone has 
an "Aha!" they might offer up.

Thanks,
MikeE
