BAND AID... Reduce the delay timer, reduce number of paging requests we send

Browse Source 
This is a band aid and not a proper fix. Reduce the time between two
IPA commands even if it is breaking rugby sized BTSs, limit the paging
commands we send during one iteration through the event loop. This should
prevent us from killing ourselves in a RACH loop.
