Merge tcp_subr.c:1.216-1.217 from HEAD to RELENG_5:

  date: 2005/01/30 23:30:28;  author: rwatson;  state: Exp;  lines: +1 -1
  Have tcp_isn_tick() fire 100 times a second, rather than HZ times a
  second; since the default hz has changed to 1000 times a second,
  this resulted in unecessary work being performed.

  Discussed with:         phk, cperciva
  General head nod:       silby

  date: 2005/01/31 01:35:01;  author: rwatson;  state: Exp;  lines: +1 -1
  Update an additional reference to the rate of ISN tick callouts that was
  missed in tcp_subr.c:1.216: projected_offset must also reflect how often
  the tcp_isn_tick() callout will fire.

  Submitted by:   silby

Note that although the default has not changed for HZ on i386 in RELENG_5,
many sites run with elevated HZ for the purposes of DUMMYNET, etc.  This
will reduce the CPU overhead of this.
