thread dump

Step to reproduce:
- Open huge project (for example chromium)
- wait parsing and checking
- Create sample "welcome"
See a long hang after "finish" button in new project wizard. It can be couple of minutes (up to 10 minutes).

Slowness in method FileBasedFileSystem.refresh() that called from MakeSampleProjectGenerator.postProcessProject().
Comment 1 Alexander Simon 2010-05-27 12:23:06 UTC 
Another test step to reproduce:
- open all modules in cnd and dlight clusters
- wait finishing scanning
- create welcome sample
See the same slowness.

The same issue occurs if you try to clean&&build Welcome when big project is opened => clean && build takes minutes to finish
