Please don't take my word for a fact when it comes to claiming
portability between gdb-4.18 and binutils-2.11.2 / gcc-3.0. I simply
used the latest version available for each tool at a certain time.

When that's said, I can confirm that the configuration seems to work
pretty well most of the time. I have seen one problem, however, that I
can't remember were there before; trying to dump a call stack trace
seem to get the debugger stuck in some endless loop.

speed. It's very robust, though. I don't think I've ever managed to
make it break down, even when I use the same pins both for debugger
communication and doing real work at the same time.
