Let me get this right.

Even stacks which do not generate IFS handles have their handles allocated
out of the same namespace as Win32 handles, and must do so to avoid clashes.
There were issues with NT prior to SP4 with the use of handles from non-IFS
providers in native Win32 calls (like ReadFile/WriteFile), but they were not
handle namespace issues.
