There are various functions in rrd_open.c (e.g. rrd_read, rrd_write)
that can be abstracted to do what is required.

However, I notice that some other files (e.g. rrd_create.c) also have
code which accesses files directly (e.g. calling open() to create a

Is there some ongoing work to centralise the file access code?  Would it
be worthwhile for me to patch some of this code (e.g. rrd_create.c) to
go through the functions in rrd_open.c, or is there some other solution
