#85
This patch fixes the occasional crash that happens in rpc.go.
The crash occurs when a reply is coming back fragmented and socket read returns an incomplete
length field or header field.
The original code is incorrect as the read loop writes at the start of the buffer at every iteration when it should write at the next position (passed the bytes already read).
ReadFull() will actually do just what is needed.
I have tested the patch and it fixes the crash (which could be reproduce very easily with prior code).
