Yes, I'm also not very eager to make "core functionality" a config option. The confusion with the INPUT layer config options was mighty, and none of it pleasant. And the *BSD's have historically had totally stupid problems with programs like Wine etc requireing kernel recompiles just because they made code functionality like vm86 mode or LDT support be a config option.
I don't see the point in dropping futexes except perhaps in a very controlled embedded environment, but if that is the case, then a PC config should just force it to "y" and not even ask the user.
We absolutely do NOT want the situation where a program will not work just because the user forgot some config option that mostly isn't needed.
And futexes _are_ going to be needed. Any sane high-performance threading implementation _will_ use them. No ifs, buts or maybe's.
