What
The SDK's memory-usage tracker, which feeds the tengu_sdk_memory_summary telemetry event, now reads each child process's memory stats from /proc/<pid>/statm asynchronously and in parallel for all child processes, using Promise.all, instead of reading them one at a time synchronously. It also computes the operating system's memory page size by rounding the ratio of resident set size to page count to the nearest power of 2, instead of doing a plain division with a fallback value of 4096.
Why
Reading memory stats in parallel rather than one-by-one should make this telemetry collection faster and less likely to block, and the improved page-size calculation should make the resulting memory measurements more accurate.
