 Library:
 ---------
 
-* Add support for fd passing in sendmsg/recvmsg.
-  Scenario:
-  We accept a connection from a client and need to pass the fd to another
-  child we forked. socket_wrapper then needs to send the 'struct socket_info'
-  to the child first and set it up there.
-  Or do it like swrap_accept() and call getpeername() and getsockname().
-* Add support for threading.
+Goals:
+* Thread safety
+* The proposed way ==> - fd-passing for tcp sockets (for free)
+  Approach:
+  - tdb "in small". So a "db file".
+    - for each socket an entry in the db file
+      (file, mmap, robust mutex. e.g. one file per local ip addr)
+    - socket_info : structure in db. protected by pthread robust mutexes
+    - socket_info_fd : --> pointer into mmap area of db
+    - free-list
+  - fd-passing: pass index in array
+    - the last element we pass is not a fd but the index number in the
+      mmaped file
 * Use realpath() in socket_wrapper_dir().
