There is an exception...
We have some clients running Lotus Domino servers under Linux under VM.
The servers would occasionally lock up and not respond. After a lot
of digging it turned out that Domino had started a long running task and
nothing else (productive) got done until that task finished.
Giving those virtual Linux servers a 2nd virtual CPU allowed Domino and
Linux to dispatch other work on the 2nd CPU and have the long running
task not impact other user work...
But that was a specific issue being addressed. In general, it buys
little if anything...

Unless you have a poorly designed application that can be fooled to
let it think it has two CPU's and thus can afford to service users in
addition to doing its background work ;-)
