Subject: The ORBit code doesn't check the number of iovec structs before it
 calls writev(2).  Some of the applications which use ORBit, such as oaf, can
 send 1214 iovecs, which is slightly more than IOV_MAX.  Add a wrapper for
 writev(2), to check the number of iovecs passed to writev, and loop, sending
 MIN(IOV_MAX, count) until the iovecs have all been written.
