So basically I have a closure called fileworker that will process a file
def fileworker = {
   open file
   parse file, adjust some values and create XML file using MarkupBuilder
   parse the created XML file using XmlParser
   upload file and XML file using HTTPBuilder
}

and this closure will be used for processing the list in parallel
(collectParallel)

groovyx.gpars.GParsPool.withPool(threads) {
                result = list.collectParallel fileworker
}

Due to my missing experiences I am a little concerned about thread
safety when GPARS comes into place ….

fileworker is self-contained from what I see, so you do not have to 
worry about concurrency issues in this case. You have to worry about 
those once you have data shared by multiple threads.
