Hi - I'm trying out btrfs again, and I see the same old bug in kernel 3.1.4
(Fedora 16, x86_64, dual-core), where after a few hours of writing, it
switches from writing with several threads to writing with one:

Ok, I'll try to reproduce this here.  Could you please do a sysrq-t, I'd
like to see what the other delalloc-writers are doing.

I'll restart the copying to get it back to its failed state and post the results when it fails.
