it always returns memory: 0 #13
Description
The runWithLimits function doesn't measure the actual memory usage of the child process; it always returns memory: 0. The previous C++ implementation used rusage to track memory consumption, which is a valuable metric for competitive programming. This is a feature regression. Consider implementing memory measurement, for example by wrapping the execution with a tool like /usr/bin/time -v on Linux and parsing its output.
