I'm looking for a good reader/writer lock in C++. We have a use case of a single infrequent writer and many frequent readers and would like to optimize for this. Preferable I would like a cross-platform solution, however a Windows only one would be acceptable.

Newer versions of boost::thread have read/write locks (1.35.0 and later, apparently the previous versions did not work correctly).

They have the names shared_lock, unique_lock, and upgrade_lock and operate on a shared_mutex.
