After it has become quiet around the project, I'm glad to announce that everything has turned to good account:

• dmd 2.052 has been out for a few weeks. Even better: It's capable of generating 64 bit binaries on Linux
• the gdc GC bugs have been fixed (see https://bitbucket.org/goshawk/gdc/issue/115/weird-memory-corruption-error-w-tls-gc)
• the test server has got a new motherboard (Supermicro X7DBE) after the original Tyan Tempest i5000PX has crocked
• I'm now using Eclipse + http://code.google.com/a/eclipselabs.org/p/ddt/ as the IDE => high productivity gain over vim

All barriers are broken down - let's focus on developing again ;-)
