fopen() seems to say it's okay...

 		 ``a''   Open for writing.  The file is created if it does not
exist.  The stream is positioned at the end of the file.  Subsequent
writes to the file will always end up at the then current end of file,
irrespective of any intervening fseek(3) or similar.


Another idea is to use syslog....
