First, would one of 'enlightened' hackers go ahead and write
meminfo.txt - description of what is what in memorymanagment?
Then: My memory probably leaks, too - but I do not know how to induce
it. I saw similar things on one notebook (with something as old as
2.1.42) - which could not compile kernel because it swapped and
swapped and swapped...
[This is 2.1.51, patched so that meminfo is compatible with older
ones. It has some more patches => more info in meminfo. I hope that my
patches are not _so_ broken to leak memory...].

Looks like at least 6Megs are missing. (Could be more due to shared
pages computed more than once.... If I do not understand that
correctly, please go ahead and write some Documentation/meminfo.txt
for me ;-)

~~~~~~~~~~~~~~~~~
What's this? I thought that this is expected to be free memory by page
size...? If so, why is 8meg free in 128kb pages, when machine is
swapping?!
