Sorry, I thought you were talking about the alias clear which simply
clears the screen.  If something is in quarantine it means:

* It is broken, not tested, and unmaintained.
* We are phasing it out.

The idea is that one of two things can happen with something in quarantine:

1.  Someone steps up and fixes it, adds tests, docs, etc. => merge it
back into the main ipython codebase.
2.  No one ever does that and eventually after some time, we move it
to "deathrow"

I don't remember why %clear got moved there, but my guess is that it
simply is broken.  Fernando may remember more of why it is there.
