A venus client without RVM is still using the same mechanisms. The only
differences are that the memory segment is allocated instead of memory
mapped off of the backing store, and modifications are not logged in the
RVM log or reapplied to the RVM data file. So it still suffers from the
same 32-bit address space and swap usage limitations.
