But as it is in the fastpath, just remove it. rand.Read() already guarantees that the value is random. 2016-12-10T10:54:36+00:00 Jakob Unterwurzacher 2016-12-10T10:50:16+00:00 urn:sha1:c9f4400e6dc71a36df5dc9725f52a8968f5f9803 We want all panics to show up in the syslog. 2016-10-04T21:18:33+00:00 Valient Gough 2016-10-02T04:14:18+00:00 urn:sha1:b764917cd5c1b1d61b8ce08e7af0b29793fbbb80 2016-06-15T21:30:44+00:00 Jakob Unterwurzacher 2016-06-15T21:30:44+00:00 urn:sha1:6c3f97399a01a2d8480b39978209099335efbf7d tlog is used heavily everywhere and deserves a shorter name.
