renable tweaked start/stop; call wait on exit

A few changes
1) restore the start/stop (old code only stopped once, otherwise the suite would stop early)
2) make a default timeout (since a few tests crash and otherwise freeze everything)
3) pull the timeout code into test
the qunit code binds start in a closure, so it isn't overriden by the one here, so we pull it out
and do it outselves
