During December 2024, Bardur worked on the com-lihaoyi/mill repository, focusing on stabilizing terminfo polling performance within the system’s runtime. He addressed a long-standing issue by implementing a solution that memoizes terminal dimensions, thereby preventing unnecessary writes and reducing both CPU and I/O load on the polling thread. This change required careful application of concurrency and performance optimization techniques in Java, ensuring that the fix preserved existing behavior while improving resource efficiency. Bardur validated the update through development and integration tests, delivering a core reliability improvement that resolved contributor concerns about excessive system load during terminal polling operations.
