Subject: Re: Re: sysconf(_SC_NPROCESSORS_CONF) broken.
interesting... in case anyone's wondering why bionic didn't use
/sys/devices/system/cpu/possible, i didn't know it existed.
i'm pretty tempted to move us over to that. not because of the
distinction between "present" and "possible" -- i'm assuming over here
in mobile those two should always be the same anyway -- but because i
can just share code with "online" and do slightly less work than the
current directory scan...
