bug in throughput?

Hello.

My SMPP connection is configured with throughput = 1

Looking at logs I see what kannel trying to do submit_sm more than 1 per second.

I have a 1 message per second limit, and carrier SMSC responds to my
high volume message flow with SMSC returned error code 0x00000008
(System Error) in response to submit_sm

As I noticed, throughput handled through gwthread_sleep() function
which is unblocked on incoming data in socket.

So, kannel do submit_sm, and then trying to sleeps for 1 second, but
that sleep is breaks by incoming data from SMSC.

Am I right or I can't get something?
