But if the server can only send 100k, send() should return this figure.
So the next time it writes, it will be the next 100k of data.  This is
how it works for me.  I just tested it, and it's sending in roughly 100k
chunks.  (Actually the first chunk is 112896 bytes, and subsequent
chunks are 96768 bytes.)

I've sent very large amounts of data over ipc before.  In fact, see the
attached demo that sends 2.5MB over ipc without any troubles.  (Tested
both with unix and tcp sockets.)  So I'll need some help reproducing the
problem.
