Comment (by jhpalmieri):
Once or twice, after running Sage, quitting, and starting it again, or
doing doctests and then running Sage, I've seen this (again, I have
allowed sage-cleaner to print its output to the screen):
{{{

Sure enough, in this case sage-cleaner isn't running while Sage is. Is
this a problem? (It does start up if asked to by `interfaces/cleaner.py`.)
I can, not very reliably, reproduce this by starting Sage, letting the
count go above 10, quit Sage, wait a second or two, and then restart it.
Otherwise, I think I'm happy with this.
