and - that temp seg isn't getting released correctly. I have only the above proof of this suspicion at the moment, but I feel this temp segment releasing error should be documented. While temp segment sizes in the process directory are small (usually 1 page long), the leak could cause the process to eventually run out of available segment numbers. The highest user process segment number allowed is segno 1777_o = 1023_d (limited by the size of user process dseg: 2 pages with each SDW in the array occupying 2 words)." defect closed major Standard Library MR12.5 fixed
