Thanks, it seems to work fine after some preliminary testing.
I use stable branch from svn revision 9510.
However, I still get these warnings on mkdir operations:

I'm unsure if it is safe to operate under such conditions. Usually slowpath

I'll keep you in touch if I'll have any faults with this issue.
