  11 Bug-Description:
  12
  13 When the `read' builtin times out after the timeout specified with -t is
  14 exceeded, it does not reset the flags that tell signal handlers to process
  15 signals immediately instead of deferring their handling.  This can result
  16 in unsafe functions being called from signal handlers, which can cause bash
  17 to hang or dump core.
