RcQueues will not work after January 5, 2012
After January 5, 2012, the method System class>>timeGmt95 will roll
over from returning a SmallInteger to returning a
LargePositiveInteger. RcQueues use this value to mark the time
elements are added to the queue, and this variable is constrained to
be a SmallInteger. Therefore, adding items to RcQueues will result
in contraint violations after January 5, 2012.
