you know, being able to start of processes from inside ant and have them
keep running afterwards would be handyish. right now I have wrapper scripts
to bring up tomcat after the build (which shuts it down before deploying)

I agree that it should be kept separate from exec because it has very
different behaviour. Its not really part of the build process any more -it
is part of the deployment/execution process.

and there are flags like 'nohup' which are kind of convenient when spawning

maybe we could have a batch file/shell script to spawn off processes in a
way appropriate for each system. It's crufty but would let us tune the
spawning as well as handling the java1.1, 1.2 'no cd on exec' issue.
