-dnl Do we have SysV SIGCLD semantics?  In other words, if we set the
-dnl action for SIGCLD to SIG_IGN does wait() always say ECHILD?  Linux,
-dnl of course, is bizarre here.  It basically implements the SysV
-dnl semantics, but if the parent calls wait() before the child calls
-dnl exit(), wait() returns with the PID of the child as normal.  (Real
-dnl SysV waits for all children to exit, then returns with ECHILD.)
-dnl Anyway, this is why the `sleep(1)' is there.
