Comment (by Michael Koch):

 It does indeed work with threads=1 as an additional parameter of blend.

 But this parameter is missing in official documentation.

 Why doesn't it work if the option -filter_threads 1 is used instead? I did
 already try that.

 Why does the geq filter work just fine with many ld() and st() in the
 expressions, without requiring any limitations to the number of threads?
