    MemoryMonitor application.

    Shows memory usage (oldspace + newspace). Simple, but useful.

    The numbers shown are:

        tot     total memory usage (i.e. allocated oldSpace + allocated newSpace)

                (does not include the second semispace and other help-areas,

                 such as the remembered set etc.)

        all     current oldSpace in use + newSpace in use

        new     current newSpace in use

        frl     free space in (fragmented) free lists

        fre     compact free area above the used oldSpace

        old     current oldSpace in use

        cod     dynamic compiled code space size (just in time compiler)

        max,    extreme values of 'tot' since the monitor started

        min     (can be reset by typing 'r' in the view)

        t       tenure threshold (1 .. 30)

        I       incremental GC state (2 = idle)

        weak    number of weak objects

        rem     size of rememberedSet

        minsc:  percent of newspace remaining after scavenge (worst case)

                (i.e. the minimum %% of scavenged objects)

        count   number of scavenges since system started

        %       percentage of live objects in newSpace after last scavenge

                (i.e. this is the garbage vs. living objects ratio of

                 newSpace objects after the last scavenge)

    the graphic shows:

        orange  newSpace used

        green   free memory in freeLists

        white   oldSpace used

    the popupMenu offers GC functions; keyboard options are:

        'f' -> faster; 's' -> slower; 'r' -> reset min/max
