+0. This is very minimal subset of Solaris libproc just enough for current application.
+Please note that the bulk of the functionality is from proc_service interface. This
+adds Pgrab__ and some missing stuff. We hide the difference b/w live process and core
+file by this interface.
+
+1. pthread_id is unique. We store this in OSThread::_pthread_id in JVM code.
+
+2. All threads see the same pid when they call getpid().
+We used to save the result of ::getpid() call in OSThread::_thread_id.
+Because gettid returns actual pid of thread (lwp id), this is
+unique again. We therefore use OSThread::_thread_id as unique identifier.
+
+3. There is a unique LWP id under both thread libraries. libthread_db  maps pthread_id
+to its underlying lwp_id under both the thread libraries. thread_info.lwp_id stores
+lwp_id of the thread. The lwp id is nothing but the actual pid of clone'd processes. But
+unfortunately libthread_db does not work very well for core dumps. So, we get pthread_id
+only for processes. For core dumps, we don't use libthread_db at all (like gdb).
+
+4. ptrace operates on this LWP id under both the thread libraries. When we say 'pid' for
+ptrace call, we refer to lwp_id of the thread.
+
+5. for core file, we parse ELF files and read data from them. For processes we  use
+combination of ptrace and /proc calls.
