Oooouch! It means that kerneld_send sleeps... It is disaster.
Even if your patch seems to be working, it will eventually destroy your system.

You can two choices:
- comment call to kerneld_send.
- patch kerneld.h.

static inline int kerneld_route(const char *ip_route)
+ if (intr_count) return NULL;
return kerneld_send(KERNELD_REQUEST_ROUTE,
strlen(ip_route), ip_route, NULL);

Your rlogin will not work from first time, just because it is
impossible for current TCP.
