The mind boggles.  We get near the end of CMDxover() and it executes 

        SendIOv(".\r\n", 3);
        PushIOv();

and if I query the vector after the first line above, the .CRLF has been 
put in the queue successfully.

(gdb) p queued_iov
$5 = 772
(gdb) p iov[771]
$6 = {iov_base = 0x817285f, iov_len = 3}
(gdb) p (char*)iov[771].iov_base
$7 = 0x817285f ".\r\n"

Yet somehow the PushIOv() doesn't result in that being written.  (The 
return value was positive, by the way, although we don't check it.)

Any thoughts on this?  


By the way, are we supposed to free the pointer OVsearch() returns in 
&data?
