                         tcp_usrreq.c tcp_var.h 
  Back out tcp_timer.c:1.93 and associated changes that reimplemented the many
  TCP timers as a single timer, but retain the API changes necessary to
  reintroduce this change.  This will back out the source of at least two
  reported problems: lock leaks in certain timer edge cases, and TCP timers
  continuing to fire after a connection has closed (a bug previously fixed and
  then reintroduced with the timer rewrite).
  In a follow-up commit, some minor restylings and comment changes performed
  after the TCP timer rewrite will be reapplied, and a further change to allow
  the TCP timer rewrite to be added back without disturbing the ABI.  The new
  design is believed to be a good thing, but the outstanding issues are
  leading to significant stability/correctness problems that are holding
  up 7.0.
  This patch was generated by silby, but is being committed by proxy due to
  poor network connectivity for silby this week.
