+RTL restrictions:
+
+ExAllocatePool (and friends) must be used exclusively. RtlAllocateHeap
(and friends) must NOT be used! ExAllocatePool (and friends) translate
to RtlAllocateHeap (and friends) in ntdll\rtl\libsupp.c.
+
+RtlEnterCriticalSection (and friends) must be used exclusively.
ExAcquireFastMutex (and friends) must NOT be used!
RtlEnterCriticalSection (and friends) translate to ExAcquireFastMutex
(and friends) in ntoskrnl\rtl\libsupp. This means that
RtlEnterCriticalSection (and friends) can NOT be used recursively in
RTL. The reason for choosing RtlEnterCriticalSection (and friends) over
ExAcquireFastMutex (and friends) is that the FAST_MUTEX struct is
smaller than the RTL_CRITICAL_SECTION struct.
