In case you don't want to re-open this issue as not fixed, I made a more
specific
report with 4097+ bytes pipes that cause a hang here:

On my install of php 5.3.9 (windows 7 wamp server 2, apache 2.2.21), the bug
has
only been fixed for 2048 to 4096 bytes. Above that, proc_open still hangs for
me.
I use the same test as above, with
$stdin = str_repeat('*', 4097 );

Log: - fixed bug #60120, proc_open's streams may hang with stdin/out/err when
the data exceeds or is equal to 2048 bytes
[2011-10-24 12:10:03] paj...@php.net
Description:
The stream used to read data from stdin/out/err hangs if the data passed is
getting larger than 2048, under certain circumstances.
Test script:
---
error_reporting(E_ALL);
$cmd = 'php -r fwrite(STDOUT, $in = file_get_contents(\'php://stdin\'));
fwrite(STDERR, $in);';
$descriptors = array(array('pipe', 'r'), array('pipe', 'w'), array('pipe',
'w'));
$stdin = str_repeat('*', 1024 * 16) . '!';
$stdin = str_repeat('*', 2049 );
$options = array_merge(array('suppress_errors' = true, 'binary_pipes' = true,
'bypass_shell' = false));
$process = proc_open($cmd, $descriptors, $pipes, getcwd(), array(), $options);
foreach ($pipes as $pipe) {
stream_set_blocking($pipe, false);
}
$writePipes = array($pipes[0]);
$stdinLen = strlen($stdin);
$stdinOffset = 0;
unset($pipes[0]);
while ($pipes || $writePipes) {
$r = $pipes;
$w = $writePipes;
$e = null;
$n = stream_select($r, $w, $e, 60);
if (false === $n) {
break;
} elseif ($n === 0) {
proc_terminate($process);
}
if ($w) {
$written = fwrite($writePipes[0], (binary)substr($stdin, $stdinOffset),
8192);
if (false !== $written) {
$stdinOffset += $written;
}
if ($stdinOffset = $stdinLen) {
fclose($writePipes[0]);
$writePipes = null;
}
}
foreach ($r as $pipe) {
$type = array_search($pipe, $pipes);
$data = fread($pipe, 8192);
if (false === $data || feof($pipe)) {
fclose($pipe);
unset($pipes[$type]);
}
}
}
