I was looking at that and thinking that my problems on Solaris 10 should not
be related to a kernel bug from dark history on Solaris 8.  This problem may
be related to this : 


I think, and this is a guess, the issue is in "ISC_SOCKET_USE_POLLWATCH".

I will do a rebuild without that defined and see what happens.  Nothing beats trial and
error :-\
