I have disabled IPv6 (a bit ?) by setting "alias net-pf-10 off" in modprobe.conf.

One system is a dual Xeon 2.4GHz system with 1GByte memory, hyperthreading on,
	swap space is not in use.
One system is a Pentium 4 2.4GHz with 512MByte of memory, swap space is not in use.
One system is an IBM 600e laptop with Pentium 2 366MHz and 256MByte of RAM, swap space is
	sometimes in use a bit.
There is no load on the systems when this occurs.

I do have KDE set to "Focus Under Mouse", I will try the systems with
this off ....
