= Summary =
When a pseudo-share is a real performance bottleneck, it is necessary to try to find and fix it, but in most applications where performance is not as critical, the existence of pseudo-shares is so little harm to the program that it is sometimes not worth the effort and extra memory space (cache line fill) to find pseudo-shares in the system. As I've always said, "Don't over-optimize, don't over-optimize." .
