…h-148509) The watcher-bits read in _PyDict_NotifyEvent needs to use acquire to synchronize with the release from PyDict_Watch so that the callback publication is visible before the callback is invoked.
Calling `connect(2)` on a non-blocking socket on WASI may leave the socket in a "connecting" but not yet "connected" state. In the former case, calling `getpeername(2)` on it will fail, leading to an unhandled exception in Python.

Transient errors can occur when attaching to a process that is actively using thread delegation (e.g. asyncio.to_thread). Add a retry loop to _get_awaited_by_tasks for RuntimeError, OSError, UnicodeDecodeError, and MemoryError, and expose --retries CLI flag on both `ps` and `pstree` subcommands (default: 3).

Treat the debug offset tables read from a target process as untrusted input and validate them before the unwinder uses any reported sizes or offsets. Add a shared validator in debug_offsets_validation.h and run it once when _Py_DebugOffsets is loaded and once when AsyncioDebug is loaded. The checks cover section sizes used for fixed local buffers and every offset that is later dereferenced against a local buffer or local object view. This keeps the bounds checks out of the sampling hot path while rejecting malformed tables up front.
…tforms (#148253) Compute ``final_depth`` in ``decode_stack_pop_push()`` and ``decode_stack_suffix()`` using ``uint64_t`` before validating it. On 32-bit builds, using ``size_t`` arithmetic for ``keep + push`` can wrap for large input values, causing the later bounds check to validate the wrong final depth. Using a widened type keeps the validation aligned with the actual result.
