What version of Cassandra? If 1.2.x, streaming has been rewritten
significantly in 2.0, and so in theory should be less likely to do this.
Note that I do not recommend upgrading to 2.0 in production at this time.

The solution you found means that the streaming part of removenode was
interrupted, which means you should repair ASAP.

Is the ticket where your input as to the desirability of a facility to
stop/restart streaming operations without restarting nodes is welcome.
