Yuki Morishita commented on CASSANDRA-7704:
-------------------------------------------

I was +1 though looks like it breaks StreamTransferTaskTest.
Let me see if I can make it work.

> See attached backtrace which was what triggered this. This stream failed and then ~12

shows all the ReadStage threads stuck inside IntervalTree.searchInternal inside of CFS.markReferenced().
