54 unique again. We therefore use OSThread::_thread_id as unique identifier.
  55 
  56 3. There is a unique LWP id under both thread libraries. libthread_db  maps pthread_id
  57 to its underlying lwp_id under both the thread libraries. thread_info.lwp_id stores
  58 lwp_id of the thread. The lwp id is nothing but the actual pid of clone'd processes. But
  59 unfortunately libthread_db does not work very well for core dumps. So, we get pthread_id
  60 only for processes. For core dumps, we don't use libthread_db at all (like gdb).
  61 
  62 4. ptrace operates on this LWP id under both the thread libraries. When we say 'pid' for
  63 ptrace call, we refer to lwp_id of the thread.
  64 
  65 5. for core file, we parse ELF files and read data from them. For processes we  use
  66 combination of ptrace and /proc calls.
