Well we exposed them to the user in the C library because people did
have a use for them. Sure you could use a separate Java APIs for doing
timeouts, but IMHO many apps will find it useful to have just one
single event loop in their program and thus want to make use of the
libvirt virEvent{Add,Update,Remove}{Handle,Timer} APIs from their
app.
