We've moved certain NSS modules such as nss_files and nss_dns into libc.  
I think there is a reasonable case that all NSS modules that aren't in 
libc (especially those not shipped with glibc) should be loaded only in a 
separate process, not in the main process doing the name lookup, to avoid 
issues with name lookup loading more or less arbitrary libraries into the 
process doing the lookup.

That doesn't say what the interface should look like to any separate 
process that handles doing lookup with not-in-libc NSS modules.
