Is there any reason that ptrace_clear_single_step is not needed ? I found that alpha implemented it, but not other architectures. For multiple threads, debugger need to turn off single step status for specific thread, I found gdb even hacked it to clear single step flag in %eflag registers on i386 because kernel does not provide a clean way to clear it.
