Good point. In fact, where I was working earlier this year, they had
several long phone calls with VMware's support, who advised them
explicitly to allocate as few cores as possible, because one VM might wait
a *lot* longer if it was looking for 4 or 8 cores, while other VMs were
using several, whereas if it only wanted 2, or 1, it would get its time
slice a lot sooner.
