:>     ram and 512MB of swap (4MB of swap in use), but the kernel reports over
:>     3 GB of VM assigned to processes.  That's a fairly lightly loaded machine.

:What you say is generally true; however, the problem is that *you*
:are making implicit assumptions about what applications *I* might
:have in mind. I just think that's a presumptous thing to do unless
:you can read minds..
:
:For example:
:
:- I might be creating a very limited embedded system with just a few
:  small processes that are all written to *handle* out of memory situations.

    Really?  Then setting resource limits from within each program is not
    a problem now is it?  Then it will get a nice malloc failure instead
    of getting killed by the kernel.

:- I could be creating a "Java OS" that is going to have a single process,
:  ie, the Java VM, that can handle ENOMEM (which translates into an
:  OutOfMemoryException, which can be caught) but otherwise *must not die*.

    .... just one process?  Set a resource limit!  If you have 64MB of swap,
    then limit the size of the Java OS process to 50MB.    Now the java
    process will get a nice malloc failure instead of getting killed by
    the kernel.
