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. -- -- Gavin Andresen
