I am not really familiar with ruby, so I came also to the C popen call,
stumbling on  the same point with reads/writes. Now I have a single
small C program doing nothing else than reading from a named pipe,
writing to a shim process which is open (and kept constantly  open) in a
popen call, which in turn  writes to a log in the file system. That
allows me to read and write from others programs asynchronously to/from
shim while still recieving asynchronously messages from tws like order
status messages, what I find sufficient.
