  SVN rev 203748 on 2010-02-10 08:50:06Z by zec
  
  MFC r203483:
    Instead of spamming the console on each curvnet recursion event, print
    out each such call graph only once, along with a stack backtrace.  This
    should make kernels built with VNET_DEBUG reasonably usable again in
    busy / production environments.
  
    Introduce a new DDB command "show vnetrcrs" which dumps the whole log
    of distinctive curvnet recursion events.  This might be useful when
    recursion reports get burried / lost too deep in the message buffer.
    In the later case stack backtraces are not available.
