Are you _certain_ that you're connecting to the same database on the
same machine when you use TCP vs unix sockets? The simplest explanation
for this problem would be that you're running different test perlu code
or running it on different machines/DBs when connecting via TCP than
when connecting via unix socket.

If that's not the case, about the only thing I can imagine is some weird
kernel security module getting in the way. Maybe something that tries to
isolate processes started as a result of tcp/ip connections so they
can't make new connections themselves, or something crazy like that. You
wouldn't happen to be on a box with SELinux/Apparmor/TOMOYO/SMACK/etc,
would you?
