#289 Reduce max. time-out value returned by tlc_getInterval

[Bernd Löhr]

The time-out value returned by tlc_getInterval is 1000s if nothing is published or subscribed with intervals or time-out values > 0. If the a separate communication thread is created before any publisher or subscriber is added, and the communication thread does not reduce this value, select() will block for 1000s. This maximum waiting time should be reduced to max. 1 s.
