I agree that this is a usability wart... though really I think the whole
idea of installing further components while Sage is running is a bad design
choice. For example, if you end up modifying shared libraries that are
currently mmaped then bad things will happen.

Yes, that seems to have solved the problem. You might want to add a

This is a bug in Maxima:
(%i2) radcan (sqrt (-1 / (u^2 + v^2 - 1))), domain=complex;

Of course it's a hack; this is why I did not submit it as a patch for Sage.
As far as one restricts oneself to the REAL DOMAIN, I think it works.
Please show me a counter-example.
