resident_size in pages, memory_size in bytes.

  I've been looking into libps today.  One thing that confuses me is that
task_basic_info.resident_size is said to be the number of resident pages of the
current task.  But in libps it seems to be used like it is the number of
resident bytes used by the current task. I'm wondering is the comment wrong in
gnumach/include/task_info.h:58 or in resident_size improperly used in libps or
I just very confused?  

  In gnumach/include/host_info.h:63 host_basic_info.memory_size is said to be
given in bytes.  The conflict seems to directly arise in hurd/libps/spec.c:247
in ps_get_rmem_frac where the resident_size is divided by the memory_size to
get the memory usage percent.
