OK, back at work and here is what I get...

4294967295 is UINT_MAX and this place is where it behaves differently on a good
kernel where the write call will succeed:

write(4, "4294967295 1352710828 0 \n", 25) = 25

P.S.: Your patched svcauth_gss.c will give me an "access denied by server"
while mounting instead of the infinite delay:
 ~/ # mount -t nfs4 -o sec=krb5 testsrv:/storage /mnt/
mount.nfs4: access denied by server while mounting testsrv:/storage
