signal.c: wrong rt signals comment, 2.4.20-pre11

I'm sorry for being a little out of date.

I believe it's the RT signals that get queued. Someone please apply
against 2.5.x?

1. 2.4.20-pre11: is there something wrong with memory accounting?

Hi guys,

Look there:
 10:45:38 up 1 day,  1:40,  2 users,  load average: 171.04, 128.12, 79.67
             total       used       free     shared    buffers     cached
Mem:        508388     505556       2832          0        580      10492
-/+ buffers/cache:     494484      13904
Swap:       996020     379696     616324
ps axl|sort -n -r +6|head -n 1
040    33  6918 20448   9   0 589505315 589505315 nanosl SL ?   0:00 [spng]

As you can see, the server has only 512Mb ram and one of processes ate 589Mb
of RSS. How could it be? A minute ago, "free" output was basically the same,
the same amount of swap was eatten, but without such a process. I see that
behaviour quite regularly. Any thoughts?
