+ *    Add changes to be a real daemon just for unix os.

+ *    process group and session leader to the own process.

+ *    Add some fatal-error log message for failed malloc().

+ *
+ *    Revision 1.25  2001/10/25 03:40:48  david__schmidt
+ *    Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
+ *    threads to call select() simultaneously.  So, it's time to do a real, live,

+ *    (native). Both versions will work, but using __OS2__ offers multi-threading.
