Unix sockets have an unfortunate historical limit of ~100 characters on
most systems. All the derivatives of 4.4BSD have a limit of 104
characters. Linux has a limit of 108 characters [1]. AIX is nice and
supports 1024 characters, but I assume you are not using that.

I guess this test can check for that error. I'll have a look.
