how many processors

[Allen, Jack]

	If you have 2 single core processors and hyper threading is
enabled, you will see 4 CPUs of information in /proc/cpuinfo.

	If you have 2 dual core processors and hyper threading is
enabled, you will see 8 CPUs of information in /proc/cpuinfo.

They must be two physical dual-core processors, right?  Do you need to
know the distinction for server maintenance purposes?
