Essentially the situation I have is this. I have a module (which also imports a number of other modules).

I have a script like:

```
import MyModule

tic()
MyModule.main()

tic()
MyModule.main()

```

In MyModule:

```
__precompile__()

module MyModule
    export main

    function main()
        toc()
        ...
    end
end

```

The first `toc()` call outputs around 20 seconds. The second outputs 2.3e-5. Can anyone offer a guess as to where the time is going? Does Julia do some kind of initialization on the first call into a module, and how can I figure out what that is?
