BTW, when I said that it works, I was talking about the original bug 
that I reported about preremove/postinstall scripts.  But I just now 
tested removing an in-use directory, and I was surprised by what 
happened.  Maybe I just don't understand how this is supposed to work. 
I have two bash shells open, with prompts $1 and $2.

In shell 1:

$1 mkdir /tmp/foo
$1 cd /tmp/foo

In shell 2:

$2 rmdir /tmp/foo
$2 ls /tmp/foo
ls: cannot access /tmp/foo: No such file or directory

Back to shell 1:

$1 ls

Is this to be expected?  I admit that it's stupid to try to list a cwd 
that no longer exists, but I would have expected a friendlier response.
