  11 Bug-Description:
  12
  13 When bash is running in Posix mode, it allows signals -- including SIGCHLD --
  14 to interrupt the `wait' builtin, as Posix requires.  However, the interrupt
  15 causes bash to not run a SIGCHLD trap for all exited children.  This patch
  16 fixes the issue and restores the documented behavior in Posix mode.
