Hello,

Indeed, this is a problem.  That's the reason why the usage of unix sockets
in listeners is still undocumented.

It's not so easy to fix, because we need to avoid the situation when the socket
is used by some other processes and avoid any possible race conditions
here.

Actually, until it will be fixed I have no better idea than put them all in the
same dedicated directory and just clean up everything in it each restart.
