No. If it had been, I wouldn't have pushed the broken fix ;-)

The whole SwDoc idle formatting has always been fragile, because the idle
document state is very distributed. This results in either no jobs run or busy
loops, like the one in the printing problem. This is just a constant problem,
if you touch code related to the Scheduler / system event loop integration.

I'll recheck, if I can change Windows to behave like the other backends, which
just run timers via the main loop and not via an extra thread. Windows has
SetTimer for this, but for whatever reason, this function has a minimum timeout
> 0, which results in other problems. Abstracting the platform behaviour to be
consistent in this regard is the main problem.

And I always check some source to see, if a LO uses a whole CPU core. With
todays HW you often doesn't realise this, as everything still runs smooth.
Since the original Scheduler work started for 5.0 we had a lot of bugs, where
Idles starved lower priority events, which also resulted in busy loops. Just
see my current painting fix for the floating, dockable toolbars.
