 Description   

It can take several seconds to destroy a joblist that used a lot of memory, and that currently blocks the main session thread in ExeMgr, meaning that the next query can't start processing until it finishes.

Make ExeMgr destroy dead joblists in a different thread so the main thread for the session can continue.
