The way we currently are handling the visibility settings for the comment form blocks is incompatible with block caching enabled.
We have to make the visibility check (wich includes a node_load()) in the operation 'visibility' instead of 'view'. To avoid multiple node_load() a static cache of that node object could be implemented.
Setting this to critical as we must fix this before a stable release.

mr.baileysnode_load() comes with it's own static caching mechanism, so the penalty for multiple calls to node_load with the same node id is negligable.
