Changes For This Release

• When terminating, call close function before reporting stats, since in the case of AIO the I/O rundown updates statistics with outstanding requests, when we're aborted by a signal.
• Setup the pattern as a pattern string, so non-modulo sizeof(u_int) read counts will data compare properly. Also fixed reopen code so it properly handles piping of stdin and stdout file descriptors. [ see example attached below ]
