I made a C++ logging library [1] that has many similarities to the LMAX disruptor. It appears to have found some use among the HFT community.

The original intent was to enable highly detailed logging without performance degradation for "post-mortem" debugging in production environments. I had coworkers who would refuse to include logging of certain important information for troubleshooting, because they were scared that it would impact performance. This put an end to that argument.
