Hello.
I get the digest of the EMC2 conversation thread,
so I apologize for not commenting immediately,
and here are a few points in the discussion that have roused me from "lurker"
status:

1.)
In the days when I could fit Windows 98 and a LINUX distribution on a six gig
drive,
I (emotionally) remember many more failures to install EMC2 on machines with
256 meg of memory,
and had much more success loaded with 320 meg.
This was from a base install, using Ubuntu 7 and 8 versions,
and may also be a YMMV issue.

2.)
I suggest this is a result of the LINUX core being upgraded.
I understand old copies and versions of LINUX core operating system binaries
are stored on the web.
Better performance would result from the core not having to make so many
decisions formatted as
(-If a multiprocessor version, then take path A otherwise take path B-).
The way out would be to choose one of the older LINUX core binaries before
multiprocessor support was incorporated,
or, identify old LINUX core binaries in 7.xx / 8.xx Ubuntu, and copy the LINUX
core binary.
Going without research at this point, I would start checking out "vmlinux".
3.)
I want to thank the EMC2 developers for evolution of product,
with regression testing.
4.)
I suggest investigating ERLANG as a potential work-along with C / Python,
because of its capability to operate in multiprocessor environments, and handle
multi thousand threads.
I admit it is a weird language.
