/*
This is a common routine for possibly forcing the send of buffered signals
and receiving response the thread is waiting for. It is designed to be
useful from:
1) PK, UK lookups using the asynchronous interface
This routine uses the wait_for_input routine instead since it has
special end conditions due to the asynchronous nature of its usage.
2) Scans
3) dictSignal
It uses a NdbWaiter object to wait on the events and this object is
linked into the conditional wait queue. Thus this object contains
a reference to its place in the queue.
It replaces the method receiveResponse previously used on the Ndb object
