Very Computer

Can someone help me please with a strange behavior
I noticed
with pppd:
Usually /var/log/messages shows me the following
after
dropping down my PPP connection:

Jun  6 17:36:23 linux pppd[2911]: Terminating on
signal 2.
Jun  6 17:36:23 linux pppd[2911]: sent [LCP
TermReq id=0x2]
Jun  6 17:36:24 linux pppd[2911]: rcvd [LCP
TermAck id=0x2]
Jun  6 17:36:24 linux pppd[2911]: Connection
terminated.
Jun  6 17:36:24 linux pppd[2911]: Exit.
Jun  6 17:37:56 linux kernel: PPP: ppp line
discipline successfully unregistered

You should notice the time gap betwen the two last
log lines: 92 seconds!!!
This seems to be the reason why sometimes the
connection establishment
is cancelled, and this only because I reconnected
immediately after
disconnecting (i.e. without waiting up to 92
seconds...).
In this case I got the following log snip:

Jun  6 17:33:44 linux pppd[2537]: Terminating on
signal 2.
Jun  6 17:33:44 linux pppd[2537]: sent [LCP

- Does someone understand why things got wrong in
this case?
- Do I always have to wait the time until
  "ppp line discipline successfully unregistered"
before
  safely reconnecting PPP?
- Is there a way to make the kernel react more
rapidly
  i.e. unregister more quickly?

Thanks for help,
Daniel.
