/*
* The goal of this test is to make sure that, after the regression introduced
* by 934bfe23a16556d05bfb1844ef4d53e8c9887c3d, the fix preserves the following
* behavior of unref timers: if two timers are scheduled to fire at the same
* time, if one unenrolls the other one in its _onTimeout callback, the other
* one will *not* fire.
*
* This behavior is a private implementation detail and should not be
* considered public interface.
