// WARNING: STATS_COUNTER_LIST_* is a very large macro that is causing MSVC
// Intellisense to crash.  It was broken into two macros (each of length 40
// lines) rather than one macro (of length about 80 lines) to work around
// this problem.  Please avoid using recursive macros of this length when
// possible.
