statLimited method
Similar to File.stat, but limits concurrency to the current semaphore limit to reduce excessive parallel I/O operations.
Helps prevent Too many open files errors and mitigates disk
contention when multiple files are accessed simultaneously.
Implementation
Future<FileStat> statLimited() async {
await _semaphore.acquire();
try {
return await stat();
} finally {
_semaphore.release();
}
}
