I assume you're referring to popen not being available. I hope that all
of System.Posix isn't being deprecated. As far as your problem, Simon
answered it well. I would suggest doing explicit I/O on pipes.
Also, I have a suggest for Posix.IO. It would be nice to have something
equivalent to hGetBuf and hPutBuf for Posix FDs. I can make handles and
use h{Get|Put}Buf, but there is extra overhead, or I can just implement
fdGetBuf and fdPutBuf. The idea is to do efficient, unbuffered I/O.
