For review: memusage(1) man page

[Alfred M. Szmidt]

   I did not "accuse" anyone of anything, but it seems clear that
   there are many cases where documentation was considered
   unimportant.

There is a different team doing work now -- what might have been in
the past is not what is now, documentation is not unimportant.

To twist it, it would be very nice to merge whatever changes,
additions, and improvments that the man pages have with regard to the
glibc manual.  Anyone who would like to take a stab at doing that?  A
good start would be a list of undocumented interfaces, tools, and
such.
