Change seek to:

		override ulong seek(long offset, SeekPos whence)
		{
			assertSeekable();
			return 0;
		}

The pipestream isn't seekable so it never returns.

After doing that you get a problem with:

		HANDLE write = INVALID_HANDLE_VALUE;
		HANDLE read = INVALID_HANDLE_VALUE;

just remove the "= INVALID.." it's not really necessary as the 
constructor always assigns values to these.

There are several string/char[] changes, eg.

1)

class ProcessException : Exception
{
	version(Windows) {
		this(string msg) { super(msg ~ ": " ~ sysErrorString(GetLastError())); }
	}
	version(linux) {	
		//for some reason getErrno does not link for me?
		this(string msg) { super(msg ~ ": " ~ 
std.string.toString(strerror(getErrno()))); }
	}
}

2)

	string readLine()
	{
		return pout.readLine();
	}
	
	string readError()
	{
		return perr.readLine();
	}

	void writeLine(string line)
	{
		pin.writeLine(line);
	}

After that I think it should compile, I can't guarantee this code works 
however ;)

Tango has a tango.sys.Pipe and tango.sys.Process which probably do very 
similar stuff.
