On my part, that was by design :-) as this comment should tell:

                                /* Give user chance to interrupt - not
                                   (currently)
                                   the gethostbyname itself, but at least
                                   the loops around it. - kw */

The "guessing" name lookups are done independently from the "regular"
name lookups.  Lynx does the latter when it tries to establish a
connection, while the "guessing" ones are done earlier, and are
implemented in a different file (src/LYUtils.c, not
.../Implementation/HTTCP.c).  Information from the guessing is not even
re-used for the later lookup (except that the nameserver and maybe the 
OS will have cached a successful lookup result, so subsequent lookups
will be faster).

Tom's patch (when I looked at it) didn't bother do deal at all with 
the "guessing" lookups (to make them interruptible), and that's fine with
me - I regard the guessing facility as somewhat of a luxury; it's not
necessary, and if you are using it you are obviously not bothered by
name lookups taking too long...

Ayway, I don't think Tom "will have to" redo the patch for this reason,
although it's fine if he does.
