Kicking off Multiple Processes from Groovy

The following is a code snippet for kicking of a number of similar processes from a Groovy script and waiting for them to finish. The stdout & stderr streams are discarded.

Normally creating interfaces with maps in Groovy when there are overloaded methods present, are non-trivial, but in this case we throw away all content. This leads to a simple nullAppender.

I just used touch as a simple illustration, replace it with whatever you need. If you want to execute your process in anotehr directory than the current worknig directory or want to customise the environment, remember that execute can take two parameters to do exactly that.
