#17 interactive prompt fails: 2.0b0

[Kelley Dagley]

Using pyMPI 2.0b0, I can only get the interactive prompt to appear
when I run with just one process. When I run with multiple
processes I get no prompt and the program exits. It works fine
with old_pyMPI.

This is fixed in the soon to be released pyMPI 2.0b4 (at
least we think it is). It should be on the download page in
a couple days(tomorrow hopefully). If you need it asap and
it's not up e-mail me and I can send you an unstable version
that works.

This is a known weirdness which is MPI version
related. Alas, the best response I can come up
with is to configure with some sledgehammer
options.

The first to try is

% ./configure --with-isatty=yes

This helps pyMPI know that a process in interactive
[often bulk launch mpirun programs hide the interactivity]

If that doesn't work, use

% ./configure --with-prompt-nl=yes

This is yuckier, but deals with the issue where
flush() doesn't work right

It adds a newline, so your prompts come out
