Hi!

In the last days, I've been and still am rather busy with other
commitments, and unfortunately have not yet been able to continue working
with you on your GSoC application as well as the GDB patch you sent.
Starting Tuesday next week, I should be able to spend more time on that.

Yes, please have a look at that. For example, do you get significantly
different test failures than I have, and how/why are they different?
Please be aware that the results from the GDB testsuite, especially when
run on GNU Hurd, are not completely "stable" (deterministic): as you can
see from the revisions of my test result files, some FAILs come and go
randomly, not related to any GDB code changes, or system environment
changes. That is, for two GDB test runs you'll get some different
results. (With time, you'll get used to quickly recognize and "ignore"
these...) ;-|

Oh, and if you want to read more about GDB's architecture and provenance,
I can recommend Stan Shebs' chapter in »The Architecture of Open Source
Applications«, <http://www.aosabook.org/en/gdb.html>.

Grüße,
Thomas
