Notification for I/O events (reads and writes on file descriptors) is done by the gobject-based event loop. File descriptors are registered with gobject with the appropriate flags for read/write/disconnect notification. Time-based events, the results of C{callLater} and C{callFromThread}, are handled differently. Rather than registering each event with gobject, a single gobject timeout is registered for the earliest scheduled event, the output of C{reactor.timeout()}. For example, if there are timeouts in 1, 2 and 3.4 seconds, a single timeout is registered for 1 second in the future. When this timeout is hit, C{_simulate} is called, which calls the appropriate Twisted-level handlers, and a new timeout is added to gobject by the C{_reschedule} method. To handle C{callFromThread} events, we use a custom waker that calls C{_simulate} whenever it wakes up. @ivar _sources: A dictionary mapping L{FileDescriptor} instances to GSource handles. @ivar _reads: A set of L{FileDescriptor} instances currently monitored for reading. @ivar _writes: A set of L{FileDescriptor} instances currently monitored for writing. @ivar _simtag: A GSource handle for the next L{simulate} call.
