Re: [annoyance/non-feature] On OS X, every process is "occupying" CWD, making disk ejects impossible after cd'ing into them.

Regardless of the merits of this proposal, OS X presents its own peculiar
set of logistical problems.  Apple stopped updating bash at bash-3.2,
since they don't like GPLv3, so any change that touched the base system
in any permanent way would have to end up going through them to backport.

If you want to set your login shell to something else (e.g.,
/usr/local/bin/bash), you could experiment with making the changes yourself
and just install your locally-modified version there.

That would only help with your shell processes; any other system process
using the shell (or, say, Finder) would not be affected.
