Re: [I] Thread deadlock in ObjectOutputStream [arrow]

pitrou commented on issue #41862:
URL: https://github.com/apache/arrow/issues/41862#issuecomment-2137587950

   Copying the temptative diagnosis I initially [posted](https://lists.apache.org/thread/d5gymtc6kj0d102k37xck8yywsyvpn7y) on the dev ML:
   
   It seems the problem lies here:
   https://github.com/apache/arrow/blob/9f5899019d23b2b1eae2fedb9f6be8827885d843/cpp/src/arrow/filesystem/s3fs.cc#L1858
   
   The Future is marked finished with the ObjectOutputStream's mutex taken, 
   and the Future's callback then triggers a chain of event which leads to 
   calling the ObjectOutputStream destructor, which in turn tries to take 
   the lock.
