There's a larger problem that a lot of layout tests aren't resilient to parser yields. This is for a variety of reasons including the one you mention.

Technically speaking, the parser can yield to service the message loop between any two tokens. Typically this doesn't happen in layout tests since tests are usually small and the parser doesn't explicitly yield until 500ms and 4,096 tokens go by. However a smaller than usual disk or network read could have the effect of sporadically introducing yields which the tests didn't expect.

One way to find all the tests which aren't resilient to parser yields is to run tests with the yielding constants in HTMLParserScheduler set so that it yields between every token:
static const int defaultParserChunkSize = 1;
static const double defaultParserTimeLimit = 0.000;

I'll try to get a list and we can try to tackle them together?
