Technical side does have problems.
1. your way to delete and check events is wrong - there is no need to
allocate new event and search for it in the hash table to remove - use
values as is.
2. initialization path has problems - hash is allocated after securty
hooks and connector moduler are registered.
3. why hash table and not rb tree?
4. are you 100% sure there are misalignments and 32/64 bit userspace
problems? you seems to copy some bits from proc connector, which
suffered from that errors in the past.
