Windows erorr reporting shows reports of crashes due to LockRecursionException
due to the following pattern:
* ASP.NET design view forces a lazy loaded tab to be populated during solution load
* That causes us to need to start pushing to workspace hosts in
  VisualStudioProjectTracker.StartPushingToWorkspaceAndNotifyOfOpenDocuments
* Ends up waiting in Workspace.OnDocumentOpened.
* Waiting pumps, and ASP.NET is finished parsing, so it tries to set the compilation options
* Workspace.OnCompilationOptionsChanged throws because the lock is the same one being waited
  on by Workspace.OnDocumentOpened.

Fixes one of the causes of internal bug 149765.
