If you use MPC to install some listings and then attempt to install more listings while P2 is still running you'll get an error message. "Cannot continue the operation. There is another install operation in progress." If p2 is already running MPC should not allow you to install any more items.
Rather than forbidding multi-install, it should be made to work : I like how it's done in iTunes or Android Playstore. Select solutions one by one, they are installed in background but while the install is proceeding I can continue browsing and schedule the next item for installation.
