I think it's the same mechanism that catches symlinked directory names, 
i.e. the shell has its own "view" to the filesystem.

For symlinked directories this is not a bug.

For this case, I don't think there's a reliable and portable way to 
catch it. The open directory is valid (since it's open) for the shell 
process, but $PWD given to other programs will make them fail. But i 
don't think a getcwd() after every command or every now and then is 
efficient.
