In the case of long replies, the read request may be broken in 2 or more
segments. 
The I/O Intr trick matches the individual "read segment" instead of the
entire reply. Is there a way to change that?
Maybe with the right settings for pollTimeout, replyTimeout, or
readTimeout? By reading the doc I suspect that setting pollTimeout
correctly should do the trick. But with me it doesn't...
