 New Comment:

I'm fine with the idea to mark this as a documentation problem, but maybe we 
should  change the length limit to something more common, like 127 or 255.
what do you think?

actullay, there is a limition, 

sys/un.h 

/* Structure describing the address of an AF_LOCAL (aka AF_UNIX) socket.  */
struct sockaddr_un
  {
    __SOCKADDR_COMMON (sun_);
    char sun_path[108];     /* Path name.  */
  };


I think this issue could mark as doc problem.

Description:
------------
this works:
./sapi/cli/php -r '$file = "/tmp/".str_repeat("a", 
101);stream_socket_server("unix://".$file) && unlink($file);'

this isn't:
./sapi/cli/php -r '$file = "/tmp/".str_repeat("a", 
102);stream_socket_server("unix://".$file) && unlink($file);'

gives me an:

Warning: stream_socket_server(): unable to connect to 
unix:///tmp/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa (Unknown error) in Command line code on line 
1

I didn't found any mention in the documentation about restrictions on the length 
of the socket file.
