[PATCH] D76240: [Sanitizers][Test] If the default linker is LLD, disable threads

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

"overwhelmed" by what, exactly?  I mean, I guess there's fundamentally some overhead if we end up with N^2 active threads (where N is the number of cores), but threads don't have that much memory overhead on their own; it shouldn't be high in absolute terms unless your test machine somehow has hundreds of cores.  And I'm not sure what else could cause an issue; I guess if the kernel scheduler decided to do something weird, context switches might hurt performance?

Also, what OS are you using?
