I had thought about it, but it's making the streams abstraction do
too much; it will have to remember too much information, and what if
the data changes each time the stream is opened?
If you really need to seek around in a stream that might not support
it, you should open a temporary stream (php_stream_fopen_tmpfile())
and then php_stream_copy_to_stream(src, tmp, PHP_STREAM_COPY_ALL)
to get a copy on disk.
When do you need to do this? Well, a general rule is when
php_stream_is(src, PHP_STREAM_IS_STDIO) is false.
