Content
The TextIOWrapper class is not thread-safe, because it calls [the equivalent of] self.buffer.write(self.pending_bytes) before clearing self.pending_bytes. Of course the write() function will release the GIL, and another thread may send the same pending_bytes again. Patch is attached. Antoine, can you review it? (_pyio.TextIOWrapper does no buffering.)
