Comment (by philip):

 The closest thing to a "specification" is probably the UNIX Network
 Programming book.  I just looked it up (page 104 and further, third
 edition).  Much historical context, but no suggestion as to what to say
 for "as many as possible".  It does say that all relevant systems will
 truncate to as large as they're prepared to accept if you specify
 something larger than that.

 I looked at the kernel side of listen() on FreeBSD, OS X and Linux, and
 they will all Do The Right Thing[tm] with that.  The fallback should catch
 anything else.

 Thanks!
