Well, you haven't mentioned open so far, but even with open, all you need is
to find out whether the request is still needed, and if not, close the fd.
If you can do it in the request callback you can also do it in the destroy
callback.
One could argue about making this automatic for those requests that create
fds, but this isn't being done at the moment.

Presumably, by looking at the request. When in doubt, initialise the
result to -1 and check whether it has been changed (it will not change if
the request was skipped).
