Added delay loop to give a newly created assembly time to appear. On
Linux (as an example), it is possible for the existence check to fail because the file is not yet recognized by the file system. Although the loop has a 250mS delay, in practise, the existence test in the for loop is successful and no delay is introduced. Next, this takes care of the two, unpredictable, situations where a script fails to compile. The first is caused by an occasional SEGV in the underlying mono VM while mcs is running, the second is caused by file system latency.
