This should be fine. Trace is stopped/aborted before you enter foo
anyway. So the tracing machinery should be reset.
You should be wary of swapcontext'ing from inside an FFI call though -
usual re-entering Lua constraint applies[1]

Will this work without BUG?
I wonder if the trace jit subsystem not support to do so.
