Latest-- 2.6.34.x seems to fix the issue, no lag whatsoever, the system is
very responsive when running rss2email, again no lag, have run 10-15 tests
without a single incident.  I also re-enabled msi and put my optimization
script back in init.d, everything continues to work perfectly.

Will wait for Adam on what went wrong with the 2.6.35 3w-9xxx update.

Justin.
