rev 12121 : [mq]: all_changes.patch


  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.
