parrot changes process foreground group, which causes grief for boutiques

[ramou]

If calling boutiques programatically, parrot causes python to suspend. The details are fuzzy, but after much fighting I found --no-set-foreground as a flag to parrot_run that removes the offending behavior.

I don't know why one would want to do this.

Interesting. It might solve another problem I had.

Will have have to put that has a default

@ramou I am finally working on adding that and updating the image build.

However it seems that the --no-set-foreground option makes the parrot_run command hang. I am trying to eliminate other source, but have tested that option and did you see that kind of behaviour?

Hrmm... I did not. I'm on vacation at this time, but come September I'll swing back to this and see what I had for that.

It seems to be a problem with the interactive session in bash. I have remove the '-i' options in the release 0.9. Might help solve the problem. --no-set-foreground was causing other strange behavior. Might have to add it as an option.
