+ o Major bugfixes (bufferevents):
+ - Apply rate-limiting only at the bottom of a chain of filtering
+ bufferevents. This prevents us from filling up internal read
+ buffers and violating rate-limits when filtering bufferevents
+ are enabled. Bugfix on 0.2.3.1-alpha; fixes part of bug 3804.
+ - Add high-watermarks to the output buffers for filtered
+ bufferevents. This prevents us from filling up internal write
+ buffers and wasting CPU cycles when filtering bufferevents are
+ enabled. Bugfix on 0.2.3.1-alpha; fixes part of bug 3804.
