Ben, Do we need the ability to set arbitrary modes? Most of the modes mentioned in the OpenSSL documentation are things we actively don’t want the user to set because stuff will randomly break. With that in mind, and with the fact that SSL_MODE_RELEASE_BUFFERS is so obviously better than the standard, should we just instead have the ssl module automatically set SSL_MODE_RELEASE_BUFFERS unconditionally? If so, I’m happy to submit a bug/patch to get that to happen. Cory
