concurrent usage of the same disk resources should be avoided

[GoogleCodeExporter]

What steps will reproduce the problem?
1. stressapptest -f stresstest -f stresstest

What is the expected output? What do you see instead?

It should start only one thread per file/device and possibly complain 
about concurrent usage of the same file. The File/device should be opened 
exclusively.

What version of the product are you using? On what operating system?
