Eliminate context switches, eliminate MMU runtime overhead (which is
quite high), reduce the need for kernel data structures (like address
space mappings and process descriptors), provide safety guarantees
within programs (not just isolation between programs), more granular
system extensions, no user-supervisor transition costs, and more.

The disadvantages are equally numerous of course, primarily being you
are stuck with the limitations of your runtime VM, whatever they may be.
