BASH PATCH REPORT
=================
Bash-Release: 3.1
Patch-ID: bash31-009
Bug-Reported-by: Joshua Neuheisel <jneuheisel@gmail.com>
Bug-Reference-ID: <25d873330601140820v4ad8efd2t8bf683b073c138b3@mail.gmail.com>
Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2006-01/msg00062.html
Bug-Description:
Under some circumstances, background (asynchronous) jobs can set the terminal
process group incorrectly. This can cause a foreground process (including
the foreground shell) to get read errors and exit.
