[erlang-questions] some language changes

[Ulf Wiger (TN/EAB)]

The problem is (1) that epp explicitly calls file:open(),
and has no function that just accepts a file descriptor,
and (2) that epp uses the io subsystem, which requires
file_io_server, which only works on regular files.

This has been discussed in an earlier thread, and 
various workarounds have been presented. Mine was to
make a ram_file_io_server, which I thought was 
trivially easy (after some study of the file IO
system).

BR,
Ulf W
