Signals are a plague. You can't write a libary which does have a
Signal-handling which is coordinatet independently from the code
it is later embedded into. Both have to be made of a single piece.
Signals are even more worse since there can't be different handlers
for synchonous signals for different threads.
And signal-codd always have a reentrancy problem, that makes them
a even bigger plague. And the ABI has to be designed around them
(red zone). That's not clean coding.
Therefore: Outsource asynchronous signals to differnt threads.
Windows has a more powerful handling for something like synchronous
signals, Structured Excetion Handling. And for the few asynchronous
signals Windows knows, Windows spawns a diffrent thread if a signal
happens.

And which threading-contol is needed beyond that what C++ provides ?
