-# Quoting unix(7) on Linux:
-#   Linux also supports an abstract namespace which is independent of the file
-#   system. [...] If sun_path starts with a null byte ('\0'), then it refers to
-#   the abstract namespace maintained by the Unix protocol module. The socket's
-#   address in this namespace is given by the rest of the bytes in sun_path.

-# By using this Linux-specific way we don't have to care about removing the
