Some versions of top only count the pages of shared memory that a
given process has actually touched so far. So for example in the
shared buffer arena, the reported usage will rise as the process runs
longer and chances to use buffers other than the ones it's used already.
It's pretty misleading, because it makes normal behavior look like a
memory leak :-(
