-"DllMain is called while the loader-lock is held. [...] You cannot call any function in
-DllMain that directly or indirectly tries to acquire the loader lock. Otherwise, you will
-introduce the possibility that your application deadlocks or crashes."
-
-it's even worse: http://msdn.microsoft.com/en-us/library/windows/desktop/ms682583(v=vs.85).aspx
-"If your DLL is linked with the C run-time library (CRT), the entry point provided by the CRT calls the constructors
-and destructors for global and static C++ objects. Therefore, these restrictions for DllMain also apply to constructors
-and destructors and any code that is called from them."

-		DLL, DllMain(): DLL_PROCESS_ATTACH
-	main thread, static object constructors
-	main thread, enter main()
-		DLL, DllMain(): DLL_THREAD_ATTACH
-		DLL, DllMain(): DLL_THREAD_DETACH
-	main thread, exit main()
-	main thread, static object destructors
-		DLL, DllMain(): DLL_PROCESS_DETACH
-		DLL, static object destructors
-
-II. dynamically linked DLL (living in main()):
-	main thread, static object constructors
-	main thread, main(): LoadLibrary
-		DLL, static object constructors
-		DLL, DllMain(): DLL_PROCESS_ATTACH
-	main thread, main(): FreeLibrary
-		DLL, DllMain(): DLL_PROCESS_DETACH
-		DLL, static object destructors
-	main thread, static object destructors

-warning: may also return with ERROR_NOT_SUPPORTED if "FileIdBothDirectoryInformation" is not supported! We need a fallback:
-
-    sometimes it's *not* sufficient to use fallback for NtQueryDirectoryFile() alone, we need to reset "hDir", since it may be fucked up by some poor file system layer implementation:
-    - Samba before v3.0.22 (Mar 30, 2006) seems to have a bug which sucessfully returns 128 elements via NtQueryDirectoryFile() and FileIdBothDirectoryInformation,
-    then fails with STATUS_INVALID_LEVEL. Fallback to FileBothDirectoryInformation will return STATUS_NO_MORE_FILES, even if there *are* more files
-    - NtQueryDirectoryFile() may *not* respect "restartScan" for some weird Win2000 file system drivers, so we cannot rely on this as a replacement for a "hDir" reset
-    - Windows 7 Remote Desktop sharing does not work unless "hDir" is reset!
-	=> let's assume worst case in general and do a reset!
-	perf note: implementing this reset at a folder level is possible, but a huge perf-killer (additional open/close handle), therefore fallback must apply to a complete folder (sub-)tree!
-	=> caller needs to handle this and implement FindFirstFile()/FindNextFile() fallback!
