LADSPA vocoder in JACK Rack has the same problem.
Being already pretty
experienced in this regard (hehehe) I can say that this is because of an
effect which I forgot how is called when the plugin stops receiving the
signal but continues to try to process data and starts going into
calculations of really small numbers and it triggers a software part of your
CPU and it uses a lot of resources, these calculations. The developer should
find a way to fix this somehow.
Your thinking of "Denormal" numbers.

A nice "quick" fix for these is:
if ( number < 0.000000001)
number = 0.0;
