According to POSIX, no, open files will not be flushed:

“The _Exit() and _exit() functions shall not call functions registered with 
atexit() nor any registered signal handlers. Open streams shall not be flushed. 
Whether open streams are closed (without flushing) is implementation-defined.”

(under the hood, os._exit() calls C _exit())
