The issue was the define ISC_SOCKET_USE_POLLWATCH.  If that is defined then we 
see the problem of strange " sockmgr 1005a1080: unexpected POLL timeout" filling
up the logs. 

Probably needed on Solaris 8 or 9 but those are getting very very old. 

Not needed on Solaris 10. 

so that was easy to sort out.
