Somebody has been inserting transactions with lots of outputs into the
main bitcoin block chain:
  http://blockexplorer.com/block/0000000000000305f98ffbe1db8445ce847fb9a924551945b465386c828f136f

Their next step will be creating transactions with thousands of inputs from those transactions. The result will be lots of excessive disk space usage.

The fix is this patch:
  https://github.com/bitcoin/bitcoin/pull/491

Suggestions on the best way to let merchants, miners, and pools know about the potential problem? I hate to take time away from the 0.4 release to re-spin 0.3.24 with the patch, but we may have to.

Is this the ArtForz solidcoin 'attack'?
