File system testing with large amounts of files.

"Waiting for slave synchronization: "
In the next version the message text changes to:
"Waiting for slave synchronization: Building and validating file structure(s) "
When Vdbench internally builds the file and directory structure there are two things that can take a while:
- Allocating about 60 bytes of memory for each file in the Java Heap, and Java doing a lot of Garbage Collection to find all that.
- If the directory structure already exists Vdbench needs to keep going to the directory to find out: "does the file exist", and 'How long is it".
This all can take quite a while if you're dealing with huge amounts of files.
