GNU Hurd

What do you think of it? It seems pretty interesting. Microkernels clearly are superior to monolithic kernels.

I dissagree, while the idea was nice the implemetation was not as good and some others stuff had been deprecated by newer better ideas

GNU Mach is complete for its purpose as a Microkernel. In that regard, there is no work needed for Mach. GNU Mach's design is outdated given the state of art in microkernel technology, that doesn't mean that Mach is no longer fit for its purpose. Now it's quite possible to update GNU Mach to match the state of art but I wouldn't bother with that. I'd prefer to fork a modern microkernel to Hurd or otherwise update Hurd to work with a modern microkernel.

I have no idea why they were not able to debug these programs

Last that I remember, Mach's network of multi-threaded servers provide plenty of opportunities for race conditions and deadlocks.
