As chair of WG2, that is exactly what I expect to see happen.  The WG
has rejected providing a complete interface to Posix (which after all
has almost 1200 functions, macros, and variables declared in over 80
header files), so I'm looking at various other Schemes to see which
parts of Posix they provide.  Similarly, WG2 will not have a complete
socket interface, but will be providing support for TCP and UDP
clients and servers (you can see my UDP proposal at
http://trac.sacrideo.us/wg/wiki/DatagramChannelsCowan; it is slightly
more convenient than raw Posix but not fundamentally different).

Placing file operations in an optional WG1 module means that WG1
implementations need not provide them, but conforms to the charter
requirement that all IEEE features be available in the WG1 language.
