DrRacket takes longer to start up on weekends

Hey all,

I want to know if I'm just imagining things or not. But DrRacket seems to take noticeably longer to start up on weekends during week days. I have a feeling this is due to the spinning racket logo that only shows up on weekends.

Has anyone else noticed this?

YES, It _IS_ actually significantly slower because of the icon.

To test this, Ben Greenman and I made a package called: `arsen`. This package is nothing but a drracket plugin that calls `exit`.

Our info file is:
```
#lang info

(define drracket-tools '(("tool.rkt")))
(define drracket-tool-names '("Arsen"))
(define drracket-tool-icons '(#f))
```

And our tool.rkt file is:
```
#lang racket/unit

(require drracket/tool)

(import drracket:tool^)
(export drracket:tool-exports^)

(define (phase1) (void))
(define (phase2) (void))

(exit)
```

Now, when we start up DrRacket, it immediately quits the moment it starts running plugins.

So, what do we get, when we run it on a Monday, we get pretty consistantly:

leif@FATT ~ $ time drracket
drracket 2.93s user 0.52s system 97% cpu 3.547 total

So 2.93 secons.

However, when we run it on a Sunday:

leif@FATT ~ $ time drracket
drracket 4.30s user 0.64s system 96% cpu 5.135 total

So 4.3 seconds.

So yes, DrRacket is in fact taking noticeably slower to launch on weekends rather than week days.

Does anyone have any suggestions on fixing it? Otherwise can we just remove the animation until its sped up?

I removed it a few minutes after your first message.
