this looks like a possible source of the problem. not privy enough about the 
spark client to assert whether that is the likely cause in that case.

Line 72:     // TODO(todd): this is weird, why are we calling completed on a -1 
seqno.
> Have you seen -1 seqno being passed here?
I suspect that might happen if the rpc failed before we try to send it (when we 
set the seqno) somehow. the callback gets called without a seqno having been 
set (and isRequestTracked only depends on the type)
