Handle Exceptions from Thread in Global Exception Handler?

I have a main application with a global exception handler installed. Now, for some specific exceptions being raised within another thread I want the global exception handler to be invoked. But it does only handle exceptions from the main thread. I also tried the following from within the thread but it does not work either:

RunInMainThread (procedure
                 begin
                 rai开发者_JS百科se EExceptionFromWithinThread.Create;
                 end);

where RunInMainThread just executes the anonymous method given as a parameter in the context of the main thread.

Why doesn't this work? What's the proper way to handle such a situation?

How about this: send a message to the main thread which exception should be raised.

I handled the exception in the thread, saving the message as a common string variable. When the status of the thread changed, I checked the variable in the main thread. Makes for very readable code.

I do this in my framework if you are interested (http://www.csinnovations.com/framework_overview.htm).
