Double-free of ivecs when sending across channel

[robarnold]

Finally found a minimal-ish testcase! This is blocking me from getting reading working for my async-io work

I bet this is the move semantics for channels issue again. Probably both ends drop the reference and then free it...

[robarnold]

I should also note that if you drop the array length to 4 and the double-free problem goes away.

Not sure if you looked at it yet but I minimized the testcase completely now.

The test case works for me now.

This was probably fixed by 54be5b0.
