Done and rebooted.

kmail is still rebuilding the indices after the reboot, but this is still 
about the same laggyness as before.

This system ran well once the initial housekeeping was finished, but this 
does appear to be, so far, pretty much a repeat with much the same long 
lags, so I don't believe this was the culprit.  I'll time it till its 
working normally and include that time in this message.

54 minutes now and kmail is still at the top of the top display.
1:08 when kmail dropped off the top line of (h)top.

So this wasn't the problem patch, you can leave it in AFAIAC.

Thanks for your patience.
