Comment(by AndreasVoellmy):
It turns out that kqueueserver2.c (mentioned in previous comments in this
item) had an error in it. Therefore, it does not indicate any problem with
kevent64. The problem in that code occurred because the program allocated
a struct kevent64_s and failed to initialize some of that struct's fields.
There must have been some garbage values in these fields that caused
kevent64 to behave oddly. The fix is to use the EV_SET64 macro to
initialize the struct.
