^-This is the one I was referring to.  Is there any reason for it to not
be in compliance with this?
"The iovcnt argument is valid if greater than 0 and less than or equal to {IOV_MAX}, as defined in
 <limits.h>" (http://www.opengroup.org/onlinepubs/007904975/)

Sorry, I just noticed that there was a previous thread here in which a
patch was submitted by balbir_soni@yahoo.com.  I think the same person
who started it might have been the same person that pointed out that one
of our LTP testcases was passing when it shouldn't be and brought it to
my attention.  It doesn't look like that thread got resolved though.
