Fatal Python error and `BufferedWriter`
When I ran the first code on windows (cygwin), I got the error on python3, but I also got an error on python2
> Unhandled exception in thread started by > sys.excepthook is missing> lost sys.stderrSo it is possible that on your platform python2.x may have silently exited the threads when they fail to acquire the lock. Also I believe that _thread module (thread in 2.7) is a low-level module and does not guarantee to avoid this behavior. From the module help
- When the main thread exits, it is system defined whether the other threads survive. On most systems, they are killed without executing try ... finally clauses or executing object destructors.
- When the main thread exits, it does not do any of its usual cleanup (except that try ... finally clauses are honored), and the standard I/O files are not flushed.
May be you should use higher level threading module with proper synchronization between main and other threads.
