The do_tcp_getsockopt() one in tpc.c is a classic case of "lots of different case statements, many of them with their own struct allocations on stack, and all of them disjoint".
Any compiler developers here? AFAIK the compiler knows the lifetime of function-local variables, so why not alias the actual memory locations and ranges to minimise stack usage?
