Multi-core systems
Multiple processors/cores. Poking around and trying to get my local server to crash has been unsuccessful but a quad processor systems seems to hang pretty often. I don't know why yet though, but it got me thinking today. With the advent of real multiprocessor systems via the explosion of dual/quad core systems instead of the fake Intel hyperthreading stuff it's entirely possible that a number of latent bugs are coming to the surface that just didn't get exposed too often on single core systems. Assuming a rare race condition it has to be more likely that this would be an issue in a dual core or dual processor system than any single core machine. If you have had repeated problems with crashes/hanging/etc please let me know what type of setup you have. Perhaps it will become obvious that multi-cores crash way more often than single cores and that will give a hint about why I have so much trouble reproducing some things locally.
