need a better file copy method

OK, so I need to do a simple file copy for a unit test.  I found a great 
code example here:

Problem is:

My test will fail roughly 50% of the time because the test's data file 
is not finished copying. I've done everything I can imagine to 
accomplish this in a synchronous manner so that I don't have to use a 
Thread.sleep(); but I can't find a way without having those intermittent 
failures.  I think this is because of the underlying file system.

Anyone know how a simple file copy can be accomplished in an explicitly 
synchronous manner without adding Thread.sleep(n) after calling flush on 
the output stream?
