    This looks like async-hooks bug now, the statwatcher emits exactly 2 events (based on the log from onchangex which is there till the end of the test) but for some reason, we get another before invocation for the 1st file. I actually tried to reproduce this on Windows 10 but to no avail, it didn't fail at even extreme values of -j --repeat.
