Question about DropTail

Hi,
when I use a DropTail queue with 'limit' one packet, no packet is
transmitted. I would like to know if there is a theoretical reason of
this behaviour or if there is a bug in drop-tail.cc line 71 
( 
	bug: if (q_->length() >= qlim_) , 
	possible correction : if (q_->length() > qlim_) 
).

Thanks.
