My favorite paper on it doing a clever workaround:
It’s a shame. The real world of development would be significantly richer if these ideas had better funding and dedicated long term development.
One of the researchers behind either rump kernels or unikernels talked to us here about making it usable. He said he was discouraged by his advisors from doing that. He could write more papers instead.
The reason they think that was is it's quantity over quality in much of academia, esp citation scores and funding for new research. Some groups seem to have their researchers use some of their time to build useful software. Most isn't production quality or maintained because they're basically paid not to do that. It's why many don't join academic research and others supported funding cuts or reform.
> DTHREADS works by exploding multithreaded applications into multiple processes, with private, copy-on-write mappings to shared memory... Experimental results show that DTHREADS substantially outperforms a state-of-the-art deterministic runtime system, and for a majority of the benchmarks evaluated here, matches and occasionally exceeds the performance of pthreads.
