Its features are as follows:
\li simple event loop interface (see section \ref eventloop)
\li wrapper functions for adding and removing file descriptors (see section \ref fdevent)
\li signal functions (TODO)
\li signal delivery through file descriptor (see section \ref signalfd)
\li timer functions (TODO)
\li safe inter-object actions (one object may free another at any time)
\li O(1) design to match that of \c epoll(7)
