Use a thread to read from the pipes. The thread can block without
disturbing the flow of the rest of the java program.
Unix pipes run sequentially as they do on windows. Unix pipes send
data as soon as the IO buffers are flushed if buffers are used, otherwise
it is delivered right away, more or less.
Without knowing more about P1 it's hard to say what exactly is possible.

Network sockets, unix sockets, pipes, IPC, and shared memory. (Dunno about
that on a linux box though. It may be a kernel compile option.)

No matter what we think of Linux versus FreeBSD, etc., the one thing I
really like about Linux is that it has Microsoft worried. Anything
that kicks a monopoly in the pants has got to be good for something.
