Processes part I: Single Processing

Make it possible for one user program to run under the control of a minimal 
operating system, and using virtual memory.

Your operating system should provide an interactive interface allowing 
the user to select which program is to run.

Example:

> load prog1.exe
> run

Your operating system must run with virtual memory turned on. That means
that unlike the example you saw coded in class, the user program (prog1.exe
above) is loaded into memory and its page tables are created while virtual
memory is enabled.

Your minimal OS should handle page faults appropriately. When a user process
needs more stack memory, it should be given it if possible. Page faults
caused by improper memory accesses should be treated as fatal errors.
