    lib/libc/include     nss_tls.h 
    lib/libc/net         nsdispatch.c nss_compat.c 
  Log:
  When a dynamic NSS module is built and linked against a thread
  library, it may pull in that thread library at run time.  If the
  process started out single-threaded, this could cause attempts to
  release locks that do not exist.  Guard against this possibility by
  checking __isthreaded before invoking thread primitives.
  
  A similar problem remains if the process is linked against one thread
  library, but the NSS module is linked against another.  This can only
  be avoided by careful design of the NSS module.
