<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>so there is no Twisted sanctioned (reactor independent and reentry safe) alternative to disable nagle (tcp nodelay) and doing a select()?<BR>
<BR>
ps: to give an example of how that was at least practically useful in what i try to do .. and not only blabbing away:<BR>

<BR>
for these 2 cases, the only difference are the calls to reactor.select()<BR>

While this is a noble goal, your method isn't really right: in TCP, the chunks you write on one end do not correspond to the chunks you receive on the other end after they've gone through a TCP stack and network. The best way to verify that your client is stream clean is to write unit tests that explicitly call its dataReceived method with different-sized chunks.<BR>
