[BUG]: Logger stream with php://stdout is stuck when the output in the same file

[eh0tka]

Bug description
If there are more than one script use in the Logger stream to "php://stdout" and both scripts run within CLI having the output into the same place ( php script.php > /dev/null or > /path/to/file.log) then one of the script becomes stuck.

It wasn't an issue with Phalcon4 and PHP 7.4 but after upgrade to Phalcon5.6 and PHP 8.2 it took a lot to identify why my queue workers are being stuck

To Reproduce

1. Write a simple infinite loop logger with while(true)
2. Launch them in parallel with the output into the same file on the disk
3. Watch the file with debug printing: it has some "NULNULNULNUL...." string and the output is almost taken but one of the worker while there is no printing from the second worker script

Steps to reproduce the behavior:

use Phalcon\Logger\Logger;
use Phalcon\Logger\Adapter\Stream as LoggerStreamAdapter;

$adapters['stdout'] = new LoggerStreamAdapter('php://stdout');

$logger = new Logger('messages', $adapters);

$num = $argv[1];

while (true) {
    $logger->info('I am here ' . $num);
    $logger->info('I am here again ' . $num);
    sleep(1);
}

Then we should launch via cli both scripts like:
php worker.php 1 > 1.log
php worker.php 2 > 1.log

[2024-03-14T11:45:58+00:00][INFO] I am here 1

Expected behavior
We expect to see printing of both 1 & 2 workers but not only one.
If we replace stream php://stdout with "echo" it works better and both printings are visible.

Details

• Phalcon version: 5.6.1
• PHP Version: 8.2.16
• Operating System: Debian 12
• Installation type: installing via package manager & compiling from source, same
• Zephir version (if any):??
• Server: Just command line

Additional context
No matter where you push stream: into the /path/to/file.log or /dev/null if this is the same output location one of the script is blocked forever on $logger->info line and never goes further
