OK, but
how do you make a program that is able to non sluggishly communicate with the
user while performing decent work (without doing performance-killing polling
stuff like "process Messages") ?
What is so performance killing about process messages ?
What do you think the OS does when switching threads ?
A thread switch is much more expensive than a "process messages".
how do you make a program doing huge calculations use multiple CPUs which are
the contrary of "of the past" ?
I didn't claim to have a better solution.
I just observed that the very idea of threads is basically flawed.
These are not my words, but the conclusion of scientific research on the
subject.
