No crashes here (so far).

Maybe it has something to do with how often the slider emits a 
value-changed signal. If it happens too often darktable continues to 
reprocesses the image...

We had that behavior in the past with gradientsliders. That's the reason 
why I added timeouts (with g_add_timeout) there. Consequence is that 
gradientsliders are much more responsive (see parametric masks, or the 
fill light module). However, there is some drawback: the marker 
sometimes lags behind the last mouse position if you stop the movement.
