        if a user program does -DFD_SETSIZE=foo, that program cannot use
        rpc(3), specifically svc_fdset and/or svc_getreqset().

        one can of course build the whole system with bigger default
        FD_SETSIZE.  but if we are to bump FD_SETSIZE in the netbsd source
        tree, that would require a libc shlib major bump due to fd_set exposed
        to the user (/usr/include/rpc/svc.h).
