Should a user be allowed to have 2 concurrent jobs that both write to the same destination?

Conversation from #337

Example:

Job in progress: x:/a/b/c/* -> y:/a

Starting new job: z:/ff/g/* -> y:/a

The big issue here is with file collisions when both jobs have the same file names. Let's say one job should create the following files

y:/a/file1.txt
y:/a/file2.txt

and the new job creates

y:/a/file2.txt
y:/a/file3.txt

They both attempt to write file2.txt
