That's really "impressive"...

I had to open 70+ tabs with "Flash" content running in order
to get Opera start using swap - on a PC with 2 GB RAM, plus
2 GB swap partition. I made a terminal capture for this
spectacular event:

  1  [||||                      7.9%]     Tasks: 73, 0 thr; 1 running
  2  [|                         2.6%]     Load average: 0.38 0.70 0.42 
  Mem[|||||||||||||||||||1601/1990MB]     Uptime: 00:52:33
  Swp[|||||               275/2047MB]

Over time, swap did increase a little bit, but hardly any
CPU load - mostly I/O load.

  Mem[|||||||||||||||||||1597/1990MB]
  Swp[||||||              404/2047MB]

The system kept being basically responsive, but the browser
was no fun to interact with until the "Flash" processes
were forcedly killed. :-)
