I am confused. We have a Model 520 with 16Meg of ram. Our size size
command also shows 20.5 Mb of .BSS ( uninitialized data space ). Even
the Unix kernel can't be using 20 megabytes of tables. I assume that
this memory MUST be used for disk cache buffers. Since real memory is
less than the buffer size AIX is paging cache buffers to disk???????
