This works smoothly to start off with, until the recv buffer on the
Linux box becomes full, at which point all write operations get queued
within the kernel until the write buffer is full, at which point the
buffer is emptied.
Have you tried setting TCP_NODELAY on the write socket? You might be
running into the Nagle algorithm with this kind of setup.
