In fact invalid report, OS problem.
The 24 seconds is spent  in single call of WinNTFileSystem.getBooleanAttributes() which is Win32 equivalent UNIX fstat, but much slower :-)

I can try to remove the critical section however it will probably block in WinNTFileSystem.getBooleanAttributes() later on.
