Hello,
This week I worked on NOTE_CREATE and IN_MOVED_* flags. These flags
required some workaround as their behavior required a little more
information than what is offered by kevent. There were few more problems
with this including the merging of events in kqueue for which I'm trying to
find a viable solution.
