 A) sometimes as root I echo to /proc/self/loginuid and it is ignored.
Why? 
Show me an example.
 There is no error message 
Not sure if '>' outputs error messages.
 B) always if I echo to /proc... as non root it is ignored (as it
should be)
 but no message is generated; shouldn't it say EPERM? 
Not sure the '>' outputs errors. You could strace it and see that the errno 
was returned and the shell did nothing with it.
 C) I put pam_loginuid in my gdm pam config but my xterm windows still
have
 -1 in loginuid (I have rebooted) 
How are you starting your xterm windows? If I use gnome terminal all is well. 
Even if I start an xterm window from it everything is still OK.
