  * Fix a bug which sometimes caused extra major GCs to be performed
  Ignore-this: 5127ff02153781823abb21fbb6f233f5
  A long-running GC would cause the timer signal to declare the system
  to be idle, which would cause a major GC immediately following the
  current GC.  This only happened with +RTS -N2 or greater.

    M ./rts/Schedule.c -12 +21
    M ./rts/sm/GC.c -6 +6
    M ./rts/sm/GC.h +1
