/*
Schedule events.
This routine will service events until the timeout expires or if MPR_SERVICE_NO_BLOCK is specified in flags,
until there are no more events to service. This routine will also return when the MPR is stopping. This will
service all enabled non-running dispatcher queues and pending I/O events.
An app should dedicate only one thread to be an event service thread.
@param timeout Time in milliseconds to wait. Set to zero for no wait. Set to -1 to wait forever.
@param flags Set to MPR_SERVICE_NO_BLOCK for non-blocking.
@returns Number of events serviced.
