Summary
- Fixed race condition in
_write_status_file_unlocked() where multiple processes could create conflicting .tmp files
- Added cleanup logic to prevent orphaned temp files on crashes or interruptions
Problem
The atomic file write used a generic .tmp suffix which could cause:
- Multiple processes overwriting each other's temp files
- Orphaned
.tmp files left behind if the process crashes between write and rename
Solution
- Use PID-specific temp file names:
status.tmp.{pid}
- Added
finally block to clean up temp file if rename fails or is interrupted
