Subject: Re-backport all the rpc stuff from glibc 2.2.5.  This allows us to
 make this junk (and I do mean that ;-) thread safe without undue pain.  Adds
 12k worth to the code size I'm afraid, but since I never use NFS and
 therefore never include this stuff, I guess thats acceptable.  I still need
 to enable the multi-threaded bits...  -Erik
