= Implement name service switch modules (NSS modules). NSS modules
may be built into libc (`static NSS modules') or dynamically loaded
via dlopen (`dynamic NSS modules'). Modules are loaded/initialized
at configuration time (i.e. when nsdispatch is called and nsswitch.conf
is read or re-read).
= Make the nsdispatch(3) core thread-safe.
= New status code for nsdispatch(3) `NS_RETURN', currently used to
signal ERANGE-type issues.
= syslog(3) problems, don't warn/err/abort.
= Try harder to avoid namespace pollution.
= Implement some shims to assist in porting NSS modules written for
the GNU C Library nsswitch interface.
