* This is what makes TOOL_MANAGER::RunSynchronousAction's spin loop safe under
* Phase D: an in-place park inside a tool body leaves a capture in flight for a
* star transfer to land on (doRewind -> "index out of bounds").
*
* extern "C" + WEAK, both load-bearing: some app builds compile this file as
* C++ (em++ keys language off the DRIVER, not the .c extension — a bare extern
* here mangles and the app aborts at "missing function" on first sleep), and
* the standalone wx test apps do not link context_sleep.cpp at all. A weak
* null resolves to "no context lane here — always yield in place", which is
* exactly the pre-context behaviour those apps pin.
