As usual? C'me on!

It was not me who pointed to "our" version of the patch.

In my original posting which Vladimir quotet I answered a question
which was exactly about the GDB version in HHL 2.0 and gdb[server]
5.2.1.

It is based on your patch, right. But your patch was against the (by
then) TOT of the GDB CVS. It was not very hard to back port to GDB
version 5.2 and even to 5.1.1. But yes, we _did_ spend some work on
this. Basic functionality of remote multi-thread debugging (namely
things as thread selection, stack backtraces, thread variables
printouts) worked okay. But if I remember right there were some
features though that were not working yet. Most notably, these were
asynchronous thread notification (that is, when gdbserver receive
signals upon creation of a new thread or death of an existing thread,
etc.), and single-stepping within a thread. Again, "we spend some
work".

Of course. Added to the README. Is this OK for you now? If not,
please send me a diff containing the text you want to see added.
