Arranges for all accesses go straight to the lowest level layer provided
by the configration. That is it strips off any layers above that layer.
(The intent - unless layers are then pushed on top again -
is to make perl's C<read> behave like C<sysread>.)

On Win32 the default in this release is "unix crlf". Win32's "stdio"
has a number of bugs/mis-features for perl IO which are somewhat

the buffer avoids those issues and makes things more uniform.
The C<crlf> layer provides CRLF to/from "\n" conversion as well as
buffering.
