Does posix_ipc's message queue thread safe & process safe? #52

For example, In the case that I create a single MessageQueue() instance and multiple processes(by multiprocessing module) share that instance, does multiple processes calling MessageQueue.send() at the same time cause race condition? I know that posix message queue itself is thread safe, but I'm not sure this wrapper of python is also safe.

Yes, it's thread safe and process safe.
