Sun research team working on mulitasking VM

A Sun research group called Barcelona have been working on a prototype of a multitasking version of the Virtual Machine.

A user can today run multiple processes each one in it’s own running VM instance, but this substantially duplicates loading of reseources, libraries, and does not effectively use resources on the host machine.

The prototype from the Sun lab allows multiple Java apps to be executed concurrently within the same VM, each process sharing resources with each other, where possible, and controlled by the VM itself.
