The documentation for Julia 0.5.0 says that the lock returned by ReentrantLock() "is NOT threadsafe" ( http://docs.julialang.org/en/release-0.5/stdlib/parallel/ see ReentrantLock()) . What does that mean? I interpret it to mean that I cannot safely call lock or unlock simultaneously with different threads, but then what good would the lock be at all?
In any case, I need a reliable mutex-style lock, but am using Julia 0.4.3 where there is no Mutex, as far as I can tell. Can I use ReentrantLock and lock and unlock? Thanks.
