Sorry, that was a bit of an exaggeration.  What actually happens with 
flvstreamer is that streaming is periodically dropped and resumed every 
time the server makes a SWF Verification request.  That can sometimes 
lead to hangs or artifacts in the recording, depending on the quality of 
your upstream connection.  Using rtmpdump prevents the continual 
dropping/resuming of the stream because it can respond to the SWF 
Verification requires.  However, rtmpdump may occasionally drop/resume 
the stream if the connection times out, etc.
