Actually there have been many successful OSes with swapping/demand paging.

A way to make it work is for process initiation to include resource
allocation, especially memory limits.  Or, you could implement the
"working set" concept according to which a process swaps only
against itself., and the maximum working set RAM is guaranteed or
the attempt to execute the process reports failure at the outset.
