        GC issues like this are currently blocking development of Visual
        D (a
        Win32 project): when just adding spaces to a file, parsing the
        new file
        every other second often needs 10 or more parsings until an
        equal amount
        of memory is collected compared to the allocated memory. AFAICT
        Visual D
        just keeps a reference to the root of the most recent AST of a
        source file.

        What's even worse: when the allocated memory gets larger (say >
        200MB),
        the garbage collection itself takes more than a second stalling the
        application, which is a real pain if it happens while you are typing
        source text (it does happen quite often).


    Can you pause the GC when the user is typing? When you're finished
    with the processing you can start it again.


There's a bit of a problem there though, when you're coding, when are
you NOT typing? :)
I don't ever stop and sit there patiently for a few seconds for no reason.

It depends. I can do quite a lot of coding without typing. But yeah, I 
type a lot. It would basically turn on and off the GC, probably not good.
