+/* This is the initializer for a "struct timeval" used in a select() call
+ * right after a new request is accept()ed to determine readablity.  Its
+ * a drop-dead timer.  Its only used for AF_UNIX sockets (not TCP sockets).
+ * Its a workaround for a kernel bug in Linux 2.0.x and SCO Unixware.
+ * Making this as small as possible, yet remain reliable would be best.
+ * 2 seconds is very conservative.  0,0 is not reliable.  The shorter the
+ * timeout, the faster request processing will recover.  The longer the
+ * timeout, the more likely this application being "busy" will cause other
+ * requests to abort and cause more dead sockets that need this timeout. */
