The latest version of Opera claims to be faster by taking advantage of "shared X memory" if I set the sysctl kern.ipc.shm_allow_removed. I don't like to change sysctls from their default settings unless I understand the consequences. I've been unable to find a manpage that describes this setting. The description "Enable/Disable attachment to attached segments marked for removal" sounds a bit frightening to me. Would anyone care to comment on the effects and risks of changing this setting on a private desktop machine?
