Comment(by anonymous):

 This bug stems from join_all() holding a mutex while giving control to
 another thread. 2067.1.patch changes this behavior. The 2067.patch does
 this too but in an unsafe way - the list of threads can change while the
 list gets iterated. A better fix might combine the two ideas - having
 shared access for read-only (keeping exclusive access for list modifying
 routines), _and_ releasing the mutex while calling join().
