Current, ppp from -current at 7 february

>Description:

When I was connected, using dial on demand, a nubmer of connections
(WEB browsing) were set up and closed. From /var/log/alias.log:
icmp=4, udp=103, tcp=5, frag_id=0 frag_ptr=0 / tot=112  (sock=0)
icmp=4, udp=104, tcp=5, frag_id=0 frag_ptr=0 / tot=113  (sock=0)
icmp=4, udp=105, tcp=5, frag_id=0 frag_ptr=0 / tot=114  (sock=0)
icmp=4, udp=106, tcp=5, frag_id=0 frag_ptr=0 / tot=115  (sock=0)

Then the connection was closed.

Somewhat later, the remembered connections were released by ppp:
icmp=3, udp=100, tcp=4, frag_id=0 frag_ptr=0 / tot=107  (sock=0)
icmp=3, udp=99, tcp=4, frag_id=0 frag_ptr=0 / tot=106  (sock=0)
icmp=3, udp=98, tcp=4, frag_id=0 frag_ptr=0 / tot=105  (sock=0)
....
icmp=3, udp=59, tcp=4, frag_id=0 frag_ptr=0 / tot=66  (sock=0)
icmp=3, udp=58, tcp=4, frag_id=0 frag_ptr=0 / tot=65  (sock=0)
icmp=3, udp=58, tcp=3, frag_id=0 frag_ptr=0 / tot=64  (sock=0)
icmp=3, udp=57, tcp=3, frag_id=0 frag_ptr=0 / tot=63  (sock=0)

During this process (forgetting the connections by the ppp 
aliasing) the dial on demand was triggered again. I didn't
trace why, but probably because of DNS lookups?

>How-To-Repeat:

Configure aliasing and dial on demand.
Do some WWW browsing. Then close the ppp dialup connection.
Wait a while.
