The "up-to-date" check is not sufficient when fetching doc comments, since a unit may have been typechecked, with doc wrapper trees removed. A test instability was due to whether the scheduler was checked by a callback or the runner thread. One sample file had no parser callbacks at all.

There was a problem hiding this comment.
would it be equivalent to add a boolean param to demandNewCompilerRun and set it true at the callsite in reload?

BTW I was curious (or annoyed) about the test; it's not my intention to muck with (or break) the PC. I assumed incorrectly that it would be a mechanism problem that required no special knowledge of PC semantics and operations. |

demandNewCompilerRuncan be refined, as it matters just for doc comments.askParseis tweaked to submit one file at a time, since otherwise the parser callback on the first job will look for work and start the next parse. (In this test, the chain stopped there because the second file was trivial and invoked no callback.)Fixes scala/scala-dev#840
