Things that survive garbage collection get promoted out of the nursery.

but being promoted to gen0 is allocation, and thus there isn't need to stop the other threads.

It's not just allocation: if it didn't get garbage collected, then there is *at least* one reference to it that needs to be updated. So what happens when there is more than one, and some of those are active in other threads? -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
