Such processes are *copmpletly* paged out to disk, and currently
have no piece of them in RAM.

I believe that is no longer the meaning of the [] brackets. Recent versions of procps use that notation to indicate kernel threads, IIRC (although I can't find definitive docs at the moment). Things that could never be swapped out (ksoftirqd and kswapd, for example) are listed in square brackets on my system. In fact, I believe pdflush from your example is a kernel thread that couldn't possibly be swapped out (it's responsible for flushing data to disk).
