UNIX socket paths seem to have a rather small limit in all operating systems.
Linux and Solaris has 108 bytes, OSX has 104 bytes. Probably increasing it
would break some programs.
Although I wonder if it would be possible to simply allocate more memory than
the struct contains and just write the string there. OSX also has some length
parameter:
unsigned char sun_len; /* sockaddr len including null */
Anyway, probably not worth the trouble.
