 * This file defines an event loop interface that supports processing events
 * from registered timeouts (i.e., do something after N seconds), sockets
 * (e.g., a new packet available for reading), and signals. eloop.c is an
 * implementation of this interface using select() and sockets. This is
 * suitable for most UNIX/POSIX systems. When porting to other operating
 * systems, it may be necessary to replace that implementation with OS specific
 * mechanisms.
