Excpected I wouldn't say so, but there is no guarantee basically. Only
long term average rate is correct, the rest is kind of up to the OS
scheduler that says when thread runs ...

At every iteration of the work() function, the block will let as much
sample pass depending on the time since the last call.
But for very very low rates (like 1k/s) that's probably not going to
go over very well because things tend to be processed by "block".
