That doesn't look right here, since leading '~' counts as absolute to
file_name_absolute_p, which is not what is wanted here.

That shouldn't matter because getcwd never returns a string starting with ~.

Why ENOTCONN? Shouldn't it be ENOENT? The failure has nothing to do with socket
connections.

I think ENOTCONN is the error returned by stat(".") if the current directory doesn't exist. But I don't care much about the exact error number, any nonzero value should do the job.
 

Also, I'd feel a bit better if we apply the workaround only to the function that
has the problem.


All of the current directory functions exhibit this behavior, including getwd and getcwd, so you need to make sure they are also covered.
