May be its because that the stream hasn't enough time to get its new
position. I didn't read streams.c/h well enough too.

In addition
[frame1.php]
<?
// Adding sleep(5) will solve the problem the first time a
// >100k File is called. The next output of a >100k File
// will crash again...
sleep(5);
header("Content-type: application/pdf\n");
readfile("some_100k_large.pdf");
?>

That last comment should let us open it back.
Removing the "big-files-passthrough" let the scripts run properly.
@Wez: can you check it? may be its because of the position of the
stream at the end of the execution of the first checksize?

The following snippets illustrate the environment
[frameset.php]
->frame1.php
->frame2.php
->frame3.php
[frame1.php]
<?
header("Content-type: application/pdf\n");
readfile("some_100k_large.pdf");
?>
[frame2.php]
<?
echo "Something";
?>
[frame3.php]
<?
echo "else";
?>

@wez: These scripts don't use sessions. They run of a CD in a
single-user-environment.
@nicos: Calling the "passthrough"-script directly works without errors.
But calling it in an frameset (together with two other scripts) crashes
when outputting a file > 100k,
The php_stream_read() returns the correct filesize.
The fact, that the parrallel execution of three scripts of one handles
a big file may be the source of the problem.
There are no write-accesses. Only Read-Accesses to small config-files.
Removing the "big-files-passthrough" let the scripts run properly.
