what is this obnoxious tree?

i have a tree in my front yard - i cant hate it too much because it's the only thing between my house and the western sun - but it's driving me NUTS!! i think either a chinese pistache or soapberry but all the googling has not mentioned my problem with it. it is sending up baby trees EVERYWHERE. they are growing under my porch, in my flower bed, coming up through my shrubs. they stink when they break over and just mowing over them creates this big nutty root that will shoot out an arm so it will just grwo 3 inches over. honestly, i dug up one root system that was two feet long. ive got one coming up through my compacted gravel driveway!!! come the nuclear winter, cockroaches will be eating their twinkies under the shade of these darned trees!! what is this thing?? edit: mystery solved. thanks everyone.
