VS Code does not cancel semantic tokens requests. If a source file gets into a state where an AST build takes very long, this can cause us to wait for the semantic tokens from sourcekitd for a few minutes, effectively blocking all other semantic functionality in that file. To circumvent this problem (or any other problem where an editor might not be cancelling requests they are no longer interested in) add a maximum request duration for SourceKitD requests, defaulting to 2 minutes. rdar://130948453
