Well, I've certainly wished for similar when writing systems that need
to run user-provided code at the same time as other user-provided code.

Also, while in most cases you could use co-routines, having a
pre-emptive system simplifies the programmer's task, and having them
implemented in the VM would yeild significantly better performance than
just using the OS's threads, I'd expect.
