Responsiveness from "inside" of some programs, not just "between" them
Typical situation - sudden computer overload by "heavy" multimedia content, most frequently this happens after opening a link in a browser leading to some page with lots of video/flash/animations, or after opening some "full-HD" multimedia file inside player, especially if computer at that moment was already near overload (then some programs could become overloaded simultaneously).
Probably the worst case - opening a multi-tabbed browser with auto-starting HD videos in (all or many) multiple tabs (this way behaves well known youtube & many other similar sites), what can happen after watching those videos consequently one by one in different tabs/windows of the same browser (this is useful if data stream ongoing from internet lags to real-time playback speed), then closing/opening that browser with "last session restore" (as usually) on.
So, how will computer with Haiku behave in such a case?
From my common knowledge about BeOS/Haiku I expect the whole OS to be controllable - that is, the ability to switch between different programs & to use those other programs to some extent should remain, but how about responsiveness of that particular overloaded program(s), which as I understand can be from "third parties" regarding OS itself, like Opera browser or VLC player, & which I know from my experience in "windows" as being not responsive - though these programs should be considered enough "progressive" among other similar ones, I don't expect their BeOS/Haiku versions to be much different in behavior than familiar "windows" versions.
If that "inside" responsiveness doesn't exist, what's the big reason of having such a "responsive" whole OS then?
How then this should be so much better than simply controlling different programs by their priority levels in windows task manager - for dealing with this new OS to be worth efforts?
