Good eyes. We read the request packets to decide if we want to flip
the .size member of the structure, but the result would not make
much sense if the structure starts with a random garbage in it.
I wonder if we can tell our compilers (or runtime checker) to help
catch a mistake like this. Did you see our sanitizers complain, or
something?
Will queue. Thanks.
