I'm thinking specifically of mission critical things like apache, but in general will other ports and such take advantage of libc_r if they are compiled with it, or would a program that _can_ take advantage of it already have that built in, say into autoconf or some such? What about other parts of the base system? I'm assuming that the kernel is covered by virtue of the fact that I've enabled the SMP options, yes? I'm trying to learn more about SMP, threads, and such like in general. The recent conversations about those topics on the lists have been very educational. I'm still wading through them, but I appreciate being able to sit on the sidelines and glean bits here and there.
