/* GNU/Linux libthread_db support.
libthread_db is a library, provided along with libpthread.so, which
exposes the internals of the thread library to a debugger. It
allows GDB to find existing threads, new threads as they are
created, thread IDs (usually, the result of pthread_self), and
thread-local variables.
The libthread_db interface originates on Solaris, where it is
both more powerful and more complicated. This implementation
only works for LinuxThreads and NPTL, the two glibc threading
libraries. It assumes that each thread is permanently assigned
to a single light-weight process (LWP).
libthread_db-specific information is stored in the "private" field
of struct thread_info. When the field is NULL we do not yet have
information about the new thread; this could be temporary (created,
but the thread library's data structures do not reflect it yet)
or permanent (created using clone instead of pthread_create).
Process IDs managed by linux-thread-db.c match those used by
linux-nat.c: a common PID for all processes, an LWP ID for each
thread, and no TID. We save the TID in private. Keeping it out
of the ptid_t prevents thread IDs changing when libpthread is
loaded or unloaded. */

was created and cannot specifically locate the event message for it.
We have to call td_ta_event_getmsg() to get
the latest message. Since we have no way of correlating whether
the event message we get back corresponds to our breakpoint, we must
loop and read all event messages, processing them appropriately.
This guarantees we will process the correct message before continuing
from the breakpoint.
Currently, death events are not enabled. If they are enabled,
the death event can use the td_thr_event_getmsg() interface to
get the message specifically for that lwp and avoid looping
