a9bebf1e14 Make idle loop not miss a chance to schedule
Prevents the case where McKernel misses one chance to schedule a
task when an interrupt occurs just after enabling interrupt and
just before executing "halt" in the idle loop (in kernel/process.c).

3f13862a98 ptrace: add error stub to prevent mcexec from waiting
In LTP's ptrace03 test,
there is a exit() preceded by ptrace(PTRACE_TRACEME).
In this case, processes will be usually finished immediately.
But mcexec will fall into waiting for parent's ptrace(PTRACE_CONT),
because mcexec sends itself a signal in processing of exit().
