A Sleep is inserted there on purpose to fix another problem of
BlackBox: 100% CPU load while selecting a text (or in any other busy
loop with call to Frame.Input - there are quite a lot of them).
Yes, Frame.Input souldn't be so inefficient. But then there should
be no busy loops with it. It's just a framework design flaw that's
not easy to fix. (Not with my BB knowledge.)

Exactly!
Another way to fix the problem is to insert that call to
Services.actionHook.Step and Sleep into every busy loop with
Frame.Input, but that would be quite an ugly patch, requiring
recompilation of most of the BB framework. I've done that for
myself, and it worked. It's just not the Right Thing to do.
I think, the framework should be redesigned a little, but I'm
not so familiar with it yet to perform such a change.
By the way, I don't want to take credit for someone else's idea.
The patch to Services and HostPorts.Rider.Input is done by Marco
Ciot ("mc" in the source comments).
