I cobbled up such a program (or pair of programs in the case) a while ago. It'd run stdin & stdout through a pty, and stderr through a seperate FIFO. I'd then run a shell within this environment. One thing I found wrt the version of bash being used was that it would not enable job control. It seems bash wanted stderr to be a pty as well, however a simple change removed that limitation in bash. .pdf
