Thanks.  I figured there was a way to do this.  I'll let you know if I
have any issues.

On a related note, I'm looking for Javadocs of the Gogo API (not the
implementation, but things like CommandProcessor).  Do those exist
anywhere?  I'm behind a firewall so grabbing the source is a real pain,
unless it can be downloaded as a zip :)

backgrounding a process causes its standard input to come from /dev/null
(or
it receives SIGSTOP when attempting to read stdin). bash behaves in
exactly
the same way:

$ bash &
[1] 81410
$
[1]+  Stopped                 bash


You need to start gogo in non-interactive mode:

g! gosh --help
gosh - execute script with arguments in a new session
  args are available as session variables $1..$9 and $args.
Usage: gosh [OPTIONS] [script-file [args..]]
  -c --command             pass all remaining args to sub-shell
     --nointeractive       don't start interactive session
     --login               login shell (same session, reads
etc/gosh_profile)
  -s --noshutdown          don't shutdown framework when script
completes
  -x --xtrace              echo commands before execution
  -? --help                show help
If no script-file, an interactive shell is started, type $D to exit.


$ java -Dgosh.args=3D--noi -jar bin/felix.jar &
