When running Servo with ASAN we hit the stack limit. We can use compile-time parsing of environment variables, to allow the embedder to configure the style thread stack size.

There was a problem hiding this comment.
Would it be possible to make this a bit simpler and just increase the stack size when ASAN is enabled?
