This is one of those cases where it might be easier to read the code than to try to explain what the code is trying to do (or to understand my poor explanation). Starting from bottom up, I'd take a look at these files: system/core/rootdir/init.rc system/core/include/cutils/sched_policy.h system/core/libcutils/sched_policy.c frameworks/base/core/jni/android_util_Process.cpp core/java/android/os/Process.java services/java/com/android/server/am/ActivityManagerService.java and probably a few more files. Also, this stuff has changed recently and will probably change again.
