+Implement a new high-frequency runtime profiler that leverages the existing
+:mod:`_remote_debugging` module to collect detailed execution statistics
+from running Python processes. This tool is exposed in the
+:mod:`profile.sample` module and enables non-intrusive observation of
+production applications by attaching to already-running processes without
+requiring any code modifications, restarts, or special startup flags. The
+observer can perform extremely high-frequency sampling of stack traces and
+interpreter state, providing detailed runtime execution analysis of live
+applications.
