Description
As described in https://groups.google.com/forum/#!topic/sage-devel/jN6inWPyElM, assume() takes more and more time the bigger the assumptions() data base is. This causes a lot of slow-downs when e.g. declaring variables with a domain argument. Nils Bruin suggested that this is due to excessive interactions with the Maxima library and Ralf Stephan suggested that the assumptions could be cached and only sent to Maxima when needed, to speed up the process.
