I guess the worse case scenario is the NEC protocol: http://www.sbprojects.com/knowledge/ir/nec.php with allows a repeat message to be sent on every 110ms. As the repeat message is 11.25 ms, that would mean a maximum time without data for 98.75 ms. So, in thesis, 100 ms would be ok. However, IR timings are not always precise and may affected by the battery charge. So, I think that a timeout of 100ms is too close to 98.75 and may cause troubles. S, IMHO, it is safer to define the default timeout as 125ms.
