Fixed eagerness issue in accum

In commit 2c06b4dcbf5c03b61f33e72b94f30bfacf9a3057 (Added Continuous
Delay SFs), I made a change to some functions in AuxFunctions to make
them more eager.  I still believe this makes sense for the delays and
timers, but it doesn't for accum and hold.  This commit fixes this.
