Changed paths: M platforms/unix/vm/aio.c
Log Message: ----------- Handle epoll event delivery errors without VM segfault. Under certain error conditions epoll may deliver event notification to the wrong process, with empty event data provided by the kernel. If this happens, handle the condition with a message to stderr and proceed without segfault. Error messages will look like this:
aioPoll in process 9055 no readHandler in epollEventData undefined handler called (fd 0, flags 2)
