Fix LockedFileError

in uv

Solution

LockedFileError in uv usually arises when a file is accessed or modified simultaneously by multiple processes or threads without proper synchronization. To fix this, ensure exclusive access to the file during critical operations using file locking mechanisms (e.g., `flock` or `fcntl`) or by coordinating file access across processes/threads with appropriate synchronization primitives like mutexes or semaphores. Specifically, review the code section raising the error, find all places that access the file, and add file locking around those regions to prevent concurrent access.
