I'm slightly worried about some external code subclassing ConditionVariable, Queue, and SizedQueue and relying on them being Structs. However, they only started being Structs with Ruby 2.1, and were implemented in pure Ruby before that; so hopefully nobody notices that implementation detail. Also, note the Mutex change as it may affect program design when space can be saved. * NEWS: entries for [Feature #13552] and [Feature #13517] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59385 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

|
Note however to always add the ",+" at the end of the argument.

|
Otherwise nothing but openssl are built. [Feature #13302]
