What? Allocate struct epoll_event on the heap?
It is a feeble joke ;)
It is an example of deliberately static storage that does not fix
your problem, thereby proving that the broken lifetimes of the
struct are not your only problem.
I explained that one at the time, and I explained this one. If it
comes with an explanation, it's probably not a joke.
```c
static int ecap__add(int fd, void *dptr)
{
struct epoll_event waitfor = {0};
int flags, r;
waitfor.data.ptr = dptr;
r = epoll_ctl(epfd, EPOLL_CTL_ADD, fd, &waitfor);
if (-1 == r) {
```
All fd's (sockets, timers etc) are added the same way
and corresponding EventSources are not destroyed by GC.
GC needs to be able to stop your program and find all of the live
objects in it. The misaligned pointer and the
reference-containing struct that vanishes on the return of your
corresponding function are both problems for this.
