It seems to be a bug in the rpc library (thank $deity for libefence
when tracking down such bugs :-). The rpcbind client code in libc
keeps a cache of DNS lookups, but it is missing a strdup() when it
copies a string from the cache.

Investigating this has shown up a few bugs I introduced to rpc.umtall
in my last set of changes, so I'll fix those too.

Ian
