[BUG] 2.4 VM sucks. Again

hi all

I've been here complaining about the 2.4 VM before, and here I am, back again.

PROBLEM:
----------------------
Starting up 30 downloads from a custom HTTP server (or Tux - or Apache -
doesn't matter), file size is 3-6GB, download speed = ~4.5Mbps. After some
time the kernel (a) goes bOOM (out of memory) if not having any swap, or (b)
goes gong swapping out anything it can.

The custom HTTP server processes each have a static buffer of two megabytes,
no malloc()s, and are written in < 1000 lines of C.

Theory: The buffer fills up, as the clients can't read as fast as kernel is
reading from disk, and the server goes boom

thanks for any help
