And the final result of all this is that setting BASH_ENV=~/.bashrc
is now a Very Bad Thing(tm).  Some of the files that get executed
when /etc/bashrc runs are themselves bash scripts.  BASH_ENV gets
used by these non-interactive scripts, and if that leads back to
/etc/bashrc again the whole thing forms an infinite loop.  Anything
in your .bashrc file that you need for non-interactive scripts
should be put in a separate file, and make _that_ the BASH_ENV
file.  You can source the BASH_ENV file from your .bashrc if you
don't want stuff duplicated in the two files.

An alternative in .bashrc is to test whether "$-" includes the
letter "i" and only source /etc/bashrc if the shell is interactive.
