I see that on some machines pipe-a-ts-continuation-suspend constantly fails as ts sequence difference is always something around 500 and not 150 which is encoded in the test. I would wonder where is this magic "150" comes from? Is is somekind of hard requirement or some calculated value? 
Should we change "150" to be calculated instead of being hardcoded?

This is fixed in:
