/* 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. */
