Pen

When pen writes its configuration file, weight
information is now
included. Weight-based server selection now works
better for small
numbers of connections.

Server weight can now be specified on the command line and displayed using the penctl command. Installation instructions for Windows were updated. A sanity check was added to the initialization code.

This release fixes a bug in the weighted server selection: server_by_weight would never consider blacklisted servers, which kept them blacklisted indefinitely.

Support for kqueue was added for BSD, offering better performance than select or poll.

Clients that are rejected by an access list can now be directed to an "abuse server". Configuration options were modified to make sure that the experimental status of the SSL support is understood.
