This is how I know it:
I constantly ping my linux server from another pc. At some poing I 
delete and recreate my queues. From the pc that pings my linux server, I 
can see the replies coming, and at the point of the restart I have 
missed pinging replies and at the point after the qdisc creation, I can 
see the icmp replies coming back again.
Either every packet is lost at qdisc removal, or something else, same as 
nasty, is happening...
You should try it and see...
Also, if you have monitor_tc running at that time, you can see it dump 
some nice negative values...
